I mean really! That's annoying! 253GB what are you! I'm a video editor, could it be my Premier projects? but shouldn't that count as movies?

That display is not an exact description of the content on your hard drive, at all. It's a rough break down, "other" is mostly your own files that happens to be categorized as "other".
If you want to get to the bottom of it, I recommend DaisyDisk, which analyze all files on the disk and present them as a sunburst diagram, you will then see exactly what it is. Just don't remove system files.

I use a program called WhatSize to track down unused files. It's great and cheap. Also there's a trial...

DaisyDisk is what use as well - it's not so great in that it doesn't allow one to select volumes. I'm seeing WhatSize for the first time - so it might be better, I dunno - they both charge $ for them. I have that "Grand Perspective" thing as well or something identical to it and I can't use it - it's just too confusing with little block all over the place too small to click on - I guess someone can get their head around it cuz it's been around for years and years.
OmniDiskSweeper is quite simple. It lets you select a volume and the scan result is is a list sorted by the biggest folders, in which you then can browse and even can double click in order to let Finder show you the folder or file.
Another one I didn't know about. But this one is more of a "cleaner" if I'm not mistaken? If that's the case I recommend caution! Every time I've used one of those in the past I've highly regretted it. All the time the system and various applications had spent creating nice quick caches has to be redone - making the system (and some applications) slow until everything is rebuilt again.![]()
OmniDiskSweeper is not a cleaner, at least not the way I use it. I use it to find big folders and files, if I have any clogging my storage drives, and then open them in Finder to do the cleaning. If one is not careful though, one could open the same folder twice.
