Do you mean memory or storage, because they're two different things. Memory is RAM, and is transitory. Storage is your hard drive or something capable of storing data on a more permanent basis.
Today, I saw my memory was at 2.00 GB so I decided to free some GBs by deleting stuff. So I deleted this file that is a Gb and then I check my space and it was 900 mb. So it was a bit weird but it didnt worry me. Then I deleted some more stuff and then I went down to 2 mb!!! Now, its 52 kb!!!!!!
What is going on? All the programs I am installing is towards my other hard drive!
