GrandPerspective: A colorful (and FREE) way to reclaim hard drive space
Earlier today I Tweeted a pic of what my hard drive looks like through the eyes of GrandPerspective, a free utility that creates a graphical representation of the sizes of the files and folders on your Mac. A couple people asked me what it was, so I figured I’d do a quick post about it.
Basically, you tell GP a location to scan on your hard drive (I just chose the whole drive) and it will graphically break down the files into size-relative blocks, showing you which files are the real space hogs on your system (scanning approximately 180,000 folders takes about 3 minutes on my MBP). Just hover your mouse over a block to see the file name and path. There is not a one-step delete from within the app (although there IS a grayed-out delete button in the interface, so maybe the functionality is coming). However, I prefer the manual way anyway, for safety’s sake. If you find something you know you don’t want sitting on your drive anymore, simply right-click on it, hit REVEAL IN FINDER, and then delete it manually.
I found a 20 GB MKV file from an old Blu-ray rip I forgot to delete using GrandPerspective, and while true Apple geeks can use terminal to search for space hogs, and the very patient can choose “Calculate Folder Sizes” in Finder and wait to see which folders might have large files, then drill through them, this is a much faster, and more fun way to reclaim drive space.
