Change Extension
Available for: Single Files

Change Extension makes it easy to view or change the extension of any file (or simply change the case of the extension).

  1. Right-click any file icon, move down to ShellToys XP, and you'll see the words Change Extension on the submenu, with the file's current extension displayed alongside.

  2. If you simply wanted to view the extension of the chosen file, you can press Esc or click outside the menu to close it.

  3. To change the extension (or change its case) click the Change Extension menu item. A dialog will appear into which you can type the required extension. You don't need to type the preceding dot (although it doesn't matter if you do). Click OK or press Enter and the selected file will have the new extension applied exactly as you typed it.

Notes:

  • If you're only changing the case of the extension, you may need to refresh the folder-window or desktop to see the effect of the change.

  • If a file with the new name already exists, a prompt will be shown to let you replace it with the renamed file. Choose Yes to delete the old file and continue the rename operation, or No to cancel.
