How to Change a File Extension From .EXE With Windows 7 64-Bit


Changing file extensions can cause problems with files, which is why Windows 7 hides file extensions by default. Changing a file extension could render the file inaccessible or prevent a file from running. However, sometimes this may be your intent. If you are unsure if a .exe file is infected with a virus but do not want to delete it, change the extension to ensure you do not accidentally run the program. To do this, you must first configure Windows to display all file extensions.

  • Hold the "Windows" key and press "E" to open Windows Explorer.

  • Click "Tools" in the top menu bar and select "Folder options." If you cannot see the top menu bar, press the "Alt" key to expose it.

  • Select the "View" tab in the Folder Options window.

  • Click to uncheck "Hide extensions for known file types" beneath "Advanced settings." Click "Apply" and then click "OK." Click the "X" in the upper-right corner of the Folder Options windows to close the window. Click within Windows Explorer to ensure it's the active window on your screen.

  • Navigate to the .exe file you want to rename in Windows Explorer, then click to select the file.

  • Press "F2" to make the file name editable.

  • Highlighted the ".exe" portion of the file name, then type the extension you want to replace it with, such as ".dat" or ".txt." Press "Enter" to accept and save the change.
