I don't have a unix server at hand, but you might be able to do it by setting up a
remote command. View - Preferences - Commands - Add
Assuming your remote box is unix/Linux/OSX the following ought to work
find /path/to/your/dir/tree -atime +XXX -exec rm {}\;
Where XXX is the number of days older than which you want to delete the files.
You may need to use the
-f
argument with
rm
to avoid problems with it trying to run interactively.
This will DELETE files, test it manually in some safe directory first.
find
is recursive so it will also include directories below the one you indicate and I think it follows links.
