view story

http://androidforums.com – I am new to this stuff and learning. I have rooted, and installed new Rom and I have moved several apps to sd card, installed new ones and put them on sd card and still my internal space shows no more space. I moved Titanium Backup to sd card and now I don't have enought space to move it back so that I can use it. Do I clear cashe or delvik? How do I get more space? I read, and searched for days before posting this. I have ex file explorer and really don't know how to use it. (General)
