Hard disk space getting eaten up

Hi, I'm fairly new to linux and am using FC6, and haven't quite got a full grasp of how the file system works. But I seem to be having a problem and don't really know what to do.

I filled up my disk space (about 7GB) and when I tried to free up space, it didn't seem to make any difference. I must have gotten rid of about 400MB but it still told me I had 0 bytes of free space. It wouldn't even let me login as regular user becuase it didn't have enough space to generate some file. I uninstalled program after program, and still no change. Finally after I deleted a folder with some pictures, it freed up about 6MB and I could login as regular user again and that's where I'm at now.

Anybody can offer some advice? I really don't know what to do, it seems like theres some thing wrong.

Linux filesystems usually have some reserved space. When the reserved space is all the free space on device, users see the device as full, but root (I mean, uid 0 user) still can write to disk. It is useful to let root still do something (having a bit of space available) when an ordinary user uses all the space on device. You've hit the limit hard by some privileged operation, and then had to go a long way to get back to normal (not quite normal, but non-fatal) disk usage.

Try df -h to see file system size. From there you can use du to find the largest folders, then the largest files, etc.
