Is it possible to Rename File Extensions?


Hi Sadah


Yes, you can Rename the File Extension. When you rename a file in a Windows, you have option to change it's extension type. That will allows you to change the file type without opening the file in a program and save it again. The default settings Windows are configured not to show the file extension when you rename a file. If you want to rename the extension, you must change the settings so that you can view the extension type. How??

First, click the "START" and then click "COMPUTER" to view the files on your computer in the Windows Explorer window.

Second, browse the Windows Explorer folders and find the file you want to rename.

Third, click the "ORGANIZE" menu in Windows Explorer and then click "FOLDER AND SEARCH OPTIONS". A new options window will open.

Forth, click the "VIEW" tab in the options window and then un-check  the "HIDE EXTENSIONS FOR KNOWN FILE TYPES" check box then click "OK".

Fifth, right-click on the file you want to rename and click "RENAME".

Sixth, delete the file's extension and type a new file extension. The file extension is displayed after the period in the file name.

Seventh, Press "ENTER" to save the new file extension.

and lastly, click "YES" in the dialog box that asks you to confirm you want to change the file.



Renaming a file extension doesn't always properly convert the file. Like, you cannot convert a text file to a video file by changing the file extension.

Is it possible to Rename File Extensions?


Yes, it is possible for you to rename some files extensions, but you have to do that with precaution. Some files will be affected negatively when you change their extensions and thus causing them to cease to work. Here is how to:

  • For image files, you will simply choose the format you want to change to and the extension will be changed. For instance, if you had a png file and you want to change to jpeg format, you will simply open the image file using an image editing application like adobe fireworks and then choose to save the file in the jpeg format.
  • For some files like word documents that have the *.doc extensions, you will have to be careful when changing their extension because the word editor can only recognize files with known extensions to it, like the *.doc extensions, and therefore changing it may make the file to malfunction.

Files that you should never attempt to change their extensions include the system files like registry entries. Changing them can make the operating system to crush.

Is it possible to Rename File Extensions?


Yes, file extensions can be renamed to something else. You can change the extension name of a file regardless of its type or contents. But be cautious when renaming file extensions because it can cause problems with applications that generally opens that file. Renaming a file extension incorrectly can also cause applications to open incorrect files.

Like for example, if you rename an executable to let’s say, an EXE file (*.exe) to a batch file (*.bat), the executable file will run since batch files can be executed but when a text editor opens the file, you will receive an error because the file is binary.

Batch files are ordinary text files that can be edited with any text editor application like Notepad while executables are binary by origin. Renaming a file extension can be done right within Windows Explorer and third-party file managers except maybe for shortcut files or LNK files (*.lnk) because the extension name is hidden in Windows Explorer which prevents renaming it.
