Freeing up space

[urvi]

It seems that over time my storage memory just seems to run out of room. I had about .1meg of free space left this morning even though i haven't installed anything news in months. Is there somewhere that junk files just build up? I checked the temp folder and the temporary internet files folder also and they are empty. I also went ahead and deleted a bunch of text messages even though i don't have that many and they don't take up any space. Any help would be appreciated.
