I've never used it this way, but RoboCopy has the ability to move files, and the ability to select them based on number of days old. You could run a batch file (or have Sesame do this when you open an app) that moves the old files to another folder, then deletes everything in that other folder.

I haven't tested it, but you might be able make RoboCopy move them directly to the Recycle Bin, making the delete step unnecessary. ???

RoboCopy is a command line utility included with Vista and Windows 7 (and Server 2008). If you don't have it, you can download it from Microsoft as part of the Windows Server 2003 Resource Kit. It's free, you just need to use IE for the download to work. Here is the link:

You might want to try some .bat file scripting. Look into the "forfiles" command. There are examples available through a google search. Also you might find that using SBasic's file commands and its string scanning and manipulation commands might serve as well.

Bummer! Forfiles is not in XP, and it is not listed in the resource kit I linked to earlier. Probably because I think it is already included with server versions of Windows.

It works great in Windows 7. But, for the article, I think I will need to keep my solution of using the "For" command, so everyone can easily make use of it.
