Based on my experience, usually they're in "\My Documents", since Microsoft assumed everything I save must go there. Ringtones, pictures, files that came through bluetooth, everything goes in there.

As if that was not enough, some applications find it useful to produce logs for every action they perform. Could you imagine an alarm application generating a >2MB worth of detailed log info?

Enough bashing, sometimes it's just the user's fault (me): I copy some files and forget where they are, so... good luck finding and deleting them. Long story short, I came up with a little tool that, for a given path, finds out folder sizes by recursively going through all subfolders.

So now, every time "my little black precious" shouts at me that it lacks storage space, I fire up this little tool, find out who are the culprits and delete them.

MTreeSize scans recursively and finds out folder sizes. If you are regularly going out of free space this little app may help you find folders with large sizes.
