Edit Extensions Dialog

You can edit the extensions assigned to a file type.

To open the edit extensions dialog

•Make sure you are in file extension mode so the file extension drop list is available for your file format of choice.

•Drop the file extension list to see all the extensions for the file format.

•At the bottom of the list is an ellipsis (...) - select it.

•The Edit Extensions Dialog will open.

The Dialog

With this dialog you can add, remove, exchange extensions with other formats.

With an extension selected in the extension list you can remove it.

When an extension is selected in the list, the extension name is copied to the extension edit box.

With a unique new extension name in the edit box, you can add a new extension.

Assigned icons for the extensions are shown in the extension list.

You can remove default extensions, but unless you need to reassign an extension to another file format this is not advised. If you have an extension that you don't want enabled for a file type, disable thumbnail enable and small icon enable instead.
