Some of my work colleagues tease me how fast I can fill up a hard drive. Yes I admit I save way more than I can review. Let's see I have digital copies of online orders, server notes, tips and tricks, documentation to read, ebooks, beta programs, and the list goes on. Right now, I only have 3 GBs of 74 GBs left. So I admit I have a problem.
So before I go on a deleting frenzy or go out out and buy another firewire/USB hard drive, let's look at the GrandPerspective. GrandPerspective is an open source Mac OS X program that gives you a nice display of how your hard drive is being used.
For example here is a screen shot:
With GrandPerspective you can scan a folder or your whole hard drive. You can sort the color by depth, folder, extension, name and top folder. On the example above, I did a scan of my home folder in Mac OS X. The big orange chunk is my Windows XP Parallels image, registering at 5.5 GBs. As you mouse over it gives you the name and size of the current file or folder.
I actually found this product when a client was looking for a corrupt file that was taking up most of his hard drive. My client was able to find the corrupt file and I found a great utility. I really enjoy using this program to see the big picture, instead of going file by file or folder by folder. Hopefully this will help you out as well.
