I've been "playing" with SpaceMonger for a few hours now and I can't find a single useful thing it will do. I get that I can perform certain tasks (copy, move, delete, etc.), but I can do that with the File Explorer. It won't search for duplicates. It hasn't got any tools (that I can find) to locate unneeded files, a la Disk Cleanup. Sure, it looks nice but that isn't really enough to make it worth the space on my crowded drive. The "help" feature is only useful if you already know what you're looking for. It's completely useless for a first time user.
