WinDirStat continues to be THE go to for me when it comes to managing file storage and I cannot recommend it enough!
See what large files and folders you've got lying around to clear and free up hard drive space; super super handy.
Just be careful of those system files and directories, they might need to stick around. 😉

@DawgNet One of the servers I manage has 7,900,000 files on it (I'm IT Manager for a large newspaper chain) I love WinDirStat, but that program choked like a gopher on a golf ball when confronted by that file server.
