Primitive File Size Chart will analyze any folder or directory and show you the largest files (or folders) in it.
If you are curious about what's eating up your hard drive space, or hogging your USB drive, running Primitive File Size Chart will give you the low down. It's a really simple, and small program, which doesn't require installation and can be run from a portable drive.
All it takes after opening is to choose the destination you'd like to scan, and then to click go. Primitive File Size Chart is pretty much as fast as you could expect, bearing in mind it scans files one by one. It took less than a minute to scan a 74 GB drive, and almost nothing for a 2GB USB drive.
Primitive File Size Chart only gives you information, so you can't delete or edit anything. That's good, as it means running the app can't damage your system, but on the other hand if you want to remove a big file, you have to go away and do it manually.
Primitive File Size Chart does exactly what it claims to, quickly and efficiently with no fuss.
