There is also the menu "Actions, List", and then putting a checkmark in "Auto-Select All Items". So then all of your files will be automatically selected each time for renaming.
Ok, got the file timestamp change to work, but there is a problem still. Looks like I have to go into every folder and subfolder to select the files first. Too time consuming that way since I have over 1500 folders. Is there a shortcut to select all files in all folders and subfolders? Thanks, Andrew
First in Filters(12) to put checkmarks only in "Files" and "Subfolder". Then click the main folder in your folder-tree. This will list all files in all sub-folders, so then you can select them all.
