Find largest files on a drive

I have a lot of folders on my pc and sometimes loose track of files and where they are. Then I get close to running out of disk space and try to look for big files to delete. Well for that purpose this tool is very useful, it will find you 100 largest files on your drive:

Very small, no install. There is probably more advanced tools for this purpose but this one was first I ran into.
