GrandPerspective is a small utility application for Mac OS X that graphically shows the disk usage within a file system. It can help you to manage your disk, as you can easily spot which files and folders take up the most space. It uses a so called tree map for visualisation. Each file is shown as a rectangle with an area proportional to the file's size. Files in the same folder appear together, but their placement is otherwise arbitrary.

Localization

GrandPerspective is fully internationalized. This means that it can be localized to support languages other than English. I can manage the translation into Dutch, but for any other language, I will need your help. So, hereby a call for volunteers. If you want to help out with making GrandPerspective available in your mother tongue, or any other language you speak fluently, find out how you can help.

Donations

You can show your appreciation for GrandPerspective and support further development by making a donation.

In order to make a donation you need an account at SourceForge.net, which is a website that provides hosting facilities for Open Source projects. SourceForge provides developers of Open Source software free of charge web site hosting, file download functionality (with mirrors across the world), mailing lists, source code management systems, bug tracking systems, user forums, etc. Donations are also handled by SourceForge and they receive a small percentage themselves. Given the amount of infrastructure that SourceForge provides free of charge, that's more than fair. Getting a SourceForge account is free, and comes without any strings attached. So, here's how to make a donation:

  1. Create a SourceForge account, if you do not already have one.

GrandPerspective is certainly not the first of its kind. Tree maps have been around for a while, and their application to file systems is not novel either. A few other disk usage visualisation tools that employ tree maps are:

So, why GrandPerspective? Well, as you may have guessed it's a fun little coding project and I needed to pick something to code on my new Mac Mini. Having said that, it does have a few things going for it. Firstly, GrandPerspective is developed specifically for Mac OS X, which narrows the immediate competition down to Disk Inventory X, as far as I'm aware. Secondly, GrandPerspective has its own way of visualising directory trees. The layout algorithm that is used is simple and effective, but novel to the best of my knowledge. Also, the file rectangles are drawn to be as clear and unobtrusive as possible. Whether you like it or not is a matter of taste, but you've got a choice. Thirdly, GrandPerspective will intentionally be kept as basic as possible. It should do one thing only, and do it well. That means it is a lean and mean application. GrandPerspective's memory requirements and the size it occupies on disk are pretty minimal. For those concerned about disk space, the latter must count for something, right? Finally, it has a cute logo that will enhance anyone's Dock. ;-)
