How to change the extension of a text document. Programs for changing file formats of various types


Hello! Lately, a lot of people started contacting me asking for help in opening a file in the form of a Word document, since users were unable to do this. When I went to their computer, I noticed that most users try to open a document with the extension “ docm" As is known, this format document contains macros and is intended for new Microsoft versions Word 2007/ 2010/ 2013. And since many people have an outdated version of Office, this created certain inconveniences.

When I answered users like this, they immediately asked the question, how can it be opened? Well, of course I started telling you that it only costs change file extension to standard and everything will work. But, before I had time to finish this, the question was asked again about how to change this extension. Of course, I told the user how this is done, without missing even the smallest details, how it is done and why, the file opened and the users were satisfied.

So, after this I decided to tell you, how can I change the extension Windows files 7, 8, 10 , because I'm sure not everyone knew about it.

What you need to change the file type extension

Before you start changing and editing the format of your files, I recommend making them backup copy, putting it on drive D and only after that proceed directly to implementing my recommendations. Why is this necessary? For example, in order to prevent further damage to documents, since there is a chance that after changing the file extension, it may not open, so the proverb: “Forewarned is forearmed” is suitable here.

So, as you know, by default in operating systems the file format is not displayed, because it is simply hidden from inexperienced users, so that they do not harm themselves. Therefore, I think you have already guessed that we should allow the file type extension to be displayed.

Method number 1:

Method number 2:


I have already written in more detail on this topic in a separate article entitled: “”.

Changing the file extension

There is nothing complicated about changing the file type extension; in principle, by following the steps that I will now show, you will see for yourself.

Having opened access to displaying the file format, click on our file, in my example it will be Word document « TEST.docm", and call context menu, where we select “ Rename».

Now for example I need to rename from docm V docx, for this I go to the name of the file extension, which is located after the dot and indicate there “ docx" After changing the file extension, the document should open in its normal form.

As I said, everything is so easy that you probably haven’t even had time to strain yourself yet. Also, in a similar way, you can change the extension of files such as: “ 7zip" on " RAR" etc. In general, if you can’t open documents in this way, then just change the file extension and you will be happy.

You listen to audio recordings every day, view hundreds of photos on the Internet, but when it comes to downloading, your computer refuses to open a file. Automatically installed programs do not support a particular format on your PC, or your phone does not open a file with your favorite image? There is no point in despair, and especially not in deleting documents. Learn how to change the file format so you don't lose data.

What is the file format

Information about the contents of the document for you and the operating system of your personal computer is the file format. When you see a certain name of a document, you already imagine what it is - music, picture, book, text, video file. The Windows operating system works on the same principle: having determined the format, it opens the file using a specific one automatically installed program. This information separated by a dot in the document name. In older versions you might have noticed this, but in newer operating systems such data is hidden.

Text documents can be of the following types: txt, doc, docx, pdf, excel, fb2, epub, djvu. Some are created using Microsoft Word, suitable for writing articles, abstracts, diplomas. Other formats are more suitable for reading books in electronic mode. Kinds graphic documents– jpg, jpeg, png, rav. The first pair is suitable for viewing regular raster and pixel images on a computer or phone, and the second pair is suitable for large-format printing. Video files can look like: avi, mp4, flv, mpeg, wmv. Audio audio tracks – mp3, wav, la (Lossless), m4a (Apple Lossless).

How to change the text file format on Windows 7, 8, 10

Manually rename file format names electronic documents It won’t work, because Windows 7, Windows 8, Windows 10 automatically hide this data. Remember that subsequent changes must be appropriate for the document type. For example, from “doc” to “docx”, from “m4a” to “m4r”. Otherwise, the computer will give you an error. To change the extension, run the following actions:

  • You will need a menu. Go to Start / Control Panel / Appearance and Personalization / Folder Options.
  • Open the “View” window, scroll to the very bottom, where we find “Hide extensions for registered file types.”
  • Uncheck the box.
  • Hooray! You can easily change text files in the name itself.

Using online converter programs

There are more simple solutions, which were invented by programmers. If you don’t want to dig into the settings to uncheck the box, and it’s more convenient for you when the extension is automatically hidden (after all, you don’t need to constantly edit it when changing the name), use special converter programs that can convert the extension in a matter of minutes. Here is a list of them for PC:

  • WinScan2PDF – converts all text files into PDF format.
  • Total PDF Converter– translates PDF documents in Doc, Excel, Text, HTML or CSV.

Often there you only need to register and upload a text, audio, video file. Here are some examples of conversion services e-books: ebook.online-convert.com, convertfileonline.com, popprograms.com, lamerkomp.ru.

Programs for changing audio and video file formats

The only caveat that stops it is that the quality may be lost. This is very disappointing if you downloaded a song for a fee in excellent resolution, but your PC detects the format as unknown or unacceptable. Use the program Format Factory(Format Factory). It is universal in use and the question of how to change the format of a video file, audio, DVD, MP4 will be solved instantly.

Converting graphic file formats

You have several options. The simplest one is to click “Save As” and set the required format for the new document. If you have on your PC graphic editor, for example, Photoshop, Corel Draw, Adobe Illustrator, then you can do the conversion like this:

  • Open the program, upload your photo there.
  • Click "Save As" and install the desired extension.
  • Don't forget to set the image size to the appropriate size.

How to change file extension in windows 7

It's no secret that our time is marked by the age of information. Right now information price is more important than ever. This is the engine of progress, the key to success and the most important component of business. In addition to the accumulation and preservation algorithm, a person needs to somehow secure information. Many software and hardware solutions have been implemented for this purpose. Speaking about the first method, here we can separate two types of protection and hiding data from the eyes of an attacker. The most simple method What can be confusing is changing the file extension.

When asking how to change a file extension in Windows 7, many users do not realize how easy it can be done. Also this function It will be useful in two more cases.

The first one will be needed for transfer certain files through email. For example, some services prohibit sending executable files(exe, bat). In this case, you can change the extension and try the transfer again.

The second case will be needed when data was downloaded from the Internet, but its expansion by for unknown reasons, does not correspond to what is needed (for example, they downloaded a book *.pdf, but it was downloaded in *.htm). Here you can try changing it to the required one and opening the file.

In Windows 7, there are two methods for replacing data extensions. All of them are quite simple and do not require specific knowledge.

The first method is “Folder Options”

There are two ways to get to this menu. The first one is the shortest. To do this, press the key combination Window + R and enter in the window that opens at the bottom left control command folders. If this command about is ignored by the operating system, you can use another way.

The second method is a little longer. Click the “Start” button and select “Control Panel”. Then, in the menu that opens at the top, for convenience, opposite the “View” section, select the “Small Icons” category. A list should appear system applications, from which you need to select “Folder Options”.

In order not to search for a long time among this multitude, you can use quick search. To do this, at the top of the window, in the appropriate field, you need to enter “Folder Options” and click Enter button.

A window will open where you need to open the “View” tab displayed at the top. Then in the list " Extra options» you need to find the item “Hide file extensions”. By default, there is a checkbox here that needs to be unchecked. Then click the “Ok” button and go to the desired file whose extension needs to be changed. Hover your mouse cursor over it and click right click, then select “Rename”. In addition to changing the name, the user will be able to change extensions. After editing, the system will ask if you really want to perform this action. Here we click the “Ok” button and see that the extension has been changed to the desired one.

The second method is “Regular Notepad”

This method is ideal for experimentation as it saves old file and creates a new one with the required extension. First, you should open the Notepad program. To do this, you can press the Window + R key combination and enter the notepad command.

If this method does not work, then the program can be found in “Start” - “All Programs” - “Accessories”. Here we select notepad. In order to change the extension, the utility must run in administrator mode.

After starting the program, click on the “File” tab and select “Open”. In the window that appears, you need to select the section at the bottom (All files (*.*)). This is necessary in order to find the necessary data other than the txt extension.

After opening the required file, notepad will most likely display a bunch of incomprehensible characters on the screen. After this, you need to open the “File” section again and select “Save As”. In this window, select from the drop-down list opposite the “File type” item - All files. Afterwards, in the field where you enter the name, you must put a dot at the end and write the required extension. Then click the “Save” button. As a result, the user will receive a data type with the old extension and the new one.

As you can see from the above, these steps are very simple. Even an inexperienced user can handle them. The only thing we can recommend is to use only the second method. Because if the file is damaged, the user will not lose data. It will be possible to continue working by changing the extension again from the “reference” file.

But in some situations, the Notepad utility cannot open certain data. In this case, you can use the first method. At the same time, make a copy of the old file.

Quite often, a file downloaded from the Internet has an extension that does not correspond to the contents of the file itself. For example, archived files with any documents have the extension not .rar, but html. We try to change the extension by simply renaming the file, but we only find the name of the file itself, and not its extension. I propose to consider the nuances of how to change the file extension in Windows 7. Of course, you can change the file extension in Windows 7 using some file manager, the same Total Commander. But if there is one in this moment on your personal computer it didn’t turn out, what should I do then?

Open any file window windows manager 7 (for example, the same My Computer) and click Alt key, the File, Edit, View, etc. menu will appear at the top of the window. IN this menu Select the “Tools” tab and select “Folder Options” from the drop-down menu.

Changing the file extension in Windows 7, 8

A file extension is a set of characters added to the end of a file name after a period that characterize the type or format and determine which program should open it. The lesson will show you how to enable, remove and change the file extension in Windows 7, 8.

The article on how to change the file type in Windows 7 discussed how to change it. Now let's remember how to enable and disable the display of the extension through folder options, registry editor.

How to show file extension in windows 7, 8 through folder properties

Open the folder properties in Windows 7, 8. Next, visit the “view” tab, there will be a long list of options. Scroll down and uncheck the box responsible for showing the extension to see it and check it to hide it.

How to enable extension display through the registry

Opening process windows registry 7 see here, windows 8 here. In the registry, go to the Advanced section. On the right side, find the HideFileExt parameter and double-click on it with the left button.

Enter a value of 0 to show the extension or 1 to hide it. Click OK and close the registry window.

There are a lot of actions to be done in the registry, so in order not to bother you, I suggest using ready-made option. Download the archive here, unpack it. As a result, you will see 2 files that have reg extension(means making changes to the registry):

  1. vkl-raschir.reg - shows the extension.
  2. otkl-raschir.reg – hides the display of the extension.

To enable display of the extension, use the file vkl-raschir.reg, right-click on it, then click “merge” in the menu. Click “yes” (if UAC appears), then “yes” (to confirm the merge) and OK (to complete the procedure).

To immediately see the file extension, click the F5 (update) button. Similarly, do the same actions with otkl-raschir.reg, if it requires it.

Once the file extension is displayed, proceed to rename it. Left-click on the file 2 times with an interval of 2 seconds, but so as not to launch it. You can also right-click on the file and select “rename”. Now you will switch to editing mode, where you will be able to not only change the file extension, but also set a new name.

Carefully remove the characters after the period. Then type the new extension, click Enter. For example, I want to create bat file, accordingly I change the extension from txt (text document) to bat (batch file).

As you can see, enabling, removing and changing extensions in Windows 7, 8 is as easy as pie and without problems. The only thing is, if you see the message “the file is already in use,” do not be alarmed, but simply close the program that is currently using it, then repeat the steps.

In what cases might this be necessary? Firstly, sometimes the size of a particular file is of great importance, and it can be different in different formats. If you need to enlarge or reduce the file, you will have to change the format. Secondly, it’s no secret that certain devices can only play certain file formats. Your phone can't read the video? Changing the video format! AND similar reasons there could be a huge number.

For my part, I will try to prove to readers that changing the file format is not at all difficult and can be done by anyone, even the most inexperienced user.

For convenience, I decided to divide my article into two main parts. In the first, I will talk about what exactly should be understood by the concept of format, and in the second, we will talk directly about how to change the format.

First of all, I note that by file format we mean a certain specification of the structure of the files recorded in computer file data. As a rule, the format is indicated in the name of the file itself as an independent part, separated from the name by a dot.

Sometimes among not very experienced users you can hear a bold statement that a file format and its extension are quite synonymous concepts. This is a huge misconception!

I will give examples. Files with the extension “.txt”, as a rule, contain some text (and only text) information. ".doc" files also include text data, but they are already properly structured and comply with Microsoft Word standards and requirements. So, both “.txt” and “.doc” have data of the same format, and therefore they are often called files belonging to the same type. And their extensions, as you can see, are different.

Part 2. How to change the file format?

Option 1. Change the file format manually.

This method is considered the simplest, but, unfortunately, it does not always work. Formally, in order to get a file in a new format, you need to change its extension. How to do it? Right-click on the file itself and select “Rename”. In the menu that opens, find the required format, give the file a new name and save it again.

Option 2. We use various converting programs.

To change audio, video or graphic file special programs called converters were created. The most common applications of this kind are ZuneConverter, SuperC, FormatFactory and many others. Follow the prompts, install one of the applications on your computer, select required file and specify the required format. The program converts your file with ease and in seconds.

Option 3. How to change the file format using online resources?

This item applies if problems arise with the installation of converter applications.

I suggest the following ways out of the situation.

It happens that install the necessary program to a computer or any other device is simply impossible. How to change the file format in this case? Easily! Turn to online converters on the Internet for help. As a rule, I use the services of websites www.zamzar.com. or www.youconvertit.com. After visiting the desired page, upload your file into the field provided. The system itself will offer you the formats available for conversion on this resource. All that remains is to choose the one that will meet all the requirements set in advance. Select the format and click the “Convert” button. The file will be changed in a matter of seconds.

What is a file extension (format)?

File extension (format)- this is the part of the file name that is separated from the main one by a dot and stands at the very end. Usually it shows what type of file it is (audio, video, picture, download file, etc.).

For example, a file called “Krab.jpg” is a picture, since it has the extension “.jpg”, and a file called “Pobeg.avi” is a video recording, since “.avi” is a video file format

I hope you get the point. Below I will write the most popular extensions and what type of file they define.

Before moving on to the topic of how to change the file format, I suggest you define file terminology. Instead of the word “format” you may also come across the word “extension”.

These are two words with equal meaning, between which you can put a mathematical equal sign, although this is not entirely correct from the point of view of mathematics:

file extension = file format

Any user sooner or later faces the need to change, and some of them find it difficult to perform this action.

You can find many special programs, with the help of which the file format is changed. Such programs are called converters. They can be freely downloaded from the Internet, or you can simply not go through the procedure of installing programs on your computer or on a device that replaces a PC.

Before we start changing the format, let’s clarify what, exactly, we are going to change.

What is a file extension (format) and why is it needed?

The file extension or format is the part of the file name that comes after the period. It is this part, which is written in the title (name) of the file, that indicates what type (format) the file belongs to.

Why is the file format needed?

The file format is needed by the operating system Windows system so that it can quickly determine which program to open a particular file for the user. And if there is no such program, then the system can inform the user that it does not understand what to do with the “strange” file.

And for what to a simple user might you need to know a little about the file extension (format)? First of all, in order to easily open files taken from the Internet or from other sources. Or just to understand that to open each file format you need a suitable program.

For example, a file named hope.txt has a .txt extension, which means it text file. Therefore, this file can be opened, for example, using , and, if necessary, make edits to it, save it with a different name, etc.

The file nadezhda.mp4 has the extension .mp4, which means we are dealing with a video file, which means that you can open, edit and, in general, deal with this format using appropriate video programs. But the Notepad program, designed for working with text, is not at all suitable for opening the video file nadezhda.mp4.

How to determine file type by format

Let me give you examples:

  • “On the sea.jpg” - we read what is written after the dot (jpg) and understand that this is an image, since jpg is an image format.
  • “Protection of the report.pptx” – we read what is written after the period (pptx) and understand that this is a presentation.
  • “Look at me.avi2” is a video file, since avi is a video file format.

Now let's look at what formats they have Various types files, so that you can also easily determine the file type by extension yourself or resort by entering a query there like “bmp what format”.

The following extensions have

  • archivers: rar, zip, arj;
  • executable programs: exe, com;
  • web pages: htm, html;
  • texts: txt, rtf, doc, docx, pdf;
  • graphics: bmp, gif, png, jpg, jpeg;
  • audio: wav, mp3, midi;
  • video: avi, mpeg, mp4.

Among the files Microsoft Office There are formats such as:

  • documents: doc, docx;
  • tables: xls, xlsx;
  • presentations: pptx, ppt, pps;
  • publications: pub.

How to open a file without knowing its format

You can simply double-click on the file with the mouse and it is likely that it will open. But this does not always happen, so automatic way let's move on to manual option in order to finally open the file.

This can be done using the context menu. Sometimes it is also called the PKM menu (menu). A context menu offers a set of specific actions that the system is able to do at the location where the user calls the menu.

Calling up the menu is simple - just right-click on the file name. On touch screens, in particular, the context menu opens if you hold your finger (or pen) in the right place, for example, on a file name.

How to change file format on Windows 7

By default, file extensions are hidden from users. Windows Developers they did this on purpose so that users wouldn’t mess things up by changing extensions, deleting “extra” files and rendering the system inoperable.

  • Hover your mouse over "
  • then go to the "Control Panel" menu
  • there click on “Small icons”,
  • then stop at the “Folder Options” item.
  • Next, the “Folder Options” window will appear, where you need to select the “View” tab (1 in Fig. 2).

  • Go lower by moving the slider (2 in Fig. 2).
  • Stop at the phrase “Hide extensions for known file types” (3 in Fig. 2).

Making a copy of the file to be on the safe side

Let's say you have a video file avi format(title.avi), and you want to convert it to mpeg format (it will be title.mpeg). Since after changing the file format, theoretically it may become inaccessible (stop opening), in this regard, I recommend making a copy of the file to be on the safe side.

  • To do this, you need to right-click on the file (right mouse button), after which a menu will appear in which you click on “Copy”.
  • Then on free space Right-click again and select “Paste” from the menu that appears.
  • The same file will appear with the word “copy” prefixed to the name, more precisely, “title - copy.avi” (1 in Fig. 3).
  • Below is an example on Windows based 7, for others Windows versions(8, 10, XP) actions are exactly the same.

Rice. 3. Make a copy of the file, then click “Rename”

It is for this new copied file that we will change the extension.

  • Click on the name “title – copy.avi” (1 in Fig. 3) with the right mouse button,
  • then click “Rename” (2 in Fig. 3).
  • And now, without changing the file name, we change only its extension, that is, after the dot, write down the format that you need, in my case it is “title - copy.mpeg”.
  • After this operation, press “Enter”, as a result we will get (Fig. 4) a duplicate of the file, or rather, a copy of it:

Rice. 5. Warning about the consequences of changing the file extension

If you are sure, then you just have to click “Yes”. Having completed these steps, all that remains is to check that the file with the new extension opens. Then you can delete extra file, which was saved under the old name, in in this example, is the title.avi file.
