Rename will rename selected files and/or folders via the chosen rename template. The Rename menu lists all user defined rename templates. Selecting one of these items while the Option key is down, will open the item in the appropriate template editor. Note that the Option function is disabled if the menu item has a keyboard shortcut with only the Option modifier.
The Rename to Initial Filename menu item will attempt to rename the selected files to the filenames they had when first loaded.
The menu may also display a submenu called Actions. Any action which is marked as being on the Rename menu in the Action Manager will be included in this menu. This is a convenience to quickly locate actions which are designed to extend the capabilities of the Rename mechanism. Selecting an action will run the action.
You can find additional information in Preferences - Rename.
Warning: If you are linked to an Apple application and the application has Preferences-Advanced/Files-Keep Media folder organized set, renaming files in Yate will more than likely not have the desired effect. When this option is set, the Apple application may rename the files back to its preferred format.
