Great!! Thanks for the tip, I used this app to do it:

I found the right folder in /mnt/ext1/applications so I cded there first.
I haven't found out how to use POterm yet, it just wouldn't start for me. But in all honesty this is probably a better solution because I can't imagine doing that much typing on the actual device!!
My apps are back now, many thanks. But what in the world is the point of clearing the games dir like that?? The theme I'm using is looking in games, not applications, so I thought I'd just move them to there...is there any way to stop that?
