After recently getting my PSP, PS3, and laptop taken away, I had no way to get on the internet, so I bought a PSP from my friend. And since my stuff has been getting taken away, I can't get on the laptop to add/delete/edit the stuff on my memory stick.

So I was wondering if it is possible to create a homebrew app that lets you:
- Delete stuff (folders, text documents etc...)
- Add stuff (folders, text documents etc...)
- Edit .txt files

Basically stuff that you can do on the computer.
