working on a friend's phone, storage is full

[slave]

I have 1.01 GB listed under Android OS, I have 2.95 GB listed under "other". I plugged it into my PC, it shows at 1gb of space, 27mb are free.

What is this other? What files are hidden? Any ideas?

The "other" are Android protected files. you can access them if you root your phone. The other is what is called EXTStorage, photos and downloaded stuff is there.
