IN information world there are more than a dozen different text formats. To work with text files, most computer users use the Microsoft Office software package. Extensive functionality, ease of editing for almost all known formats And constant updates allowed Microsoft Word become the most popular document editor. Since there is no single format for text files, users often have questions about how to change the format of a text document. Are you faced with an “unreadable” format or do you urgently need to change the format?..

Before you start changing the file format, you need to understand the difference between a document format and its extension. The format is the contents of the file, and the extension is just a set of letters that tell the system which program should open the file. For example, if the file has the extension .avi, then Windows will open it with the default video player.

Changing the format of Word documents

To change the format of a text document, it is recommended to use the built-in capabilities Microsoft editor Word. Open the document in any version of Office, click on the “File” button at the top of the screen and select the “Save As” tab.

In the drop-down list, specify the format in which you want to save the file. Select a location to save the new file and click “Save.”

In this way, you can “translate” any Word document into the desired format.

If you need to change the format of a txt file, then it is much easier to change the file extension. But first you need to enable the display of extensions in Windows. Open My Computer and press the Alt button on your keyboard. In the line that appears, click on the “Tools” button and go to the “Folder Options” tab.

In the new “Folder Options” window, go to the “View” tab, scroll through the list “ Extra options" to the end and uncheck the box "Hide extensions for known file types." Then click the “Apply” button, followed by “OK”.

Click on the text file right click mouse and context menu select Rename. For example, if a text file in .txt format is changed to .html, the file will already open in the browser.

In the same way, you can “translate” a txt file into .doc or .rtf format. But if you try to rename the extension of any Word document in .txt, problems will arise when opening the file.

If you don’t have the Microsoft Office software package at hand, you can use special conversion utilities or online services.

If it suddenly turns out that the file stopped opening, this does not mean that it has deteriorated, but that the selected program does not know how to work with it.

For example, psd image it is forbidden reformat to jpg because it supports layers, which jpg does not. There are a number of others reasons, to which the standard Windows solution Photos will report that it "Cannot open the file." Here you will need specialized software, such as Photoshop.

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 “Advanced options” list you need to find the “Hide file extensions” item. By default, there is a checkbox here that needs to be unchecked. Then click the “Ok” button and go to the required file, which needs to change the extension. Hover the mouse cursor over it and 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 required file, the 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 he can deal with them inexperienced user. 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.
