Disk Graph

With Disk Graph you can inspect your disk and easily find the files that take away most of your disk space or haven’t been modified in a long time.

Download on the Mac App Store

You can select any volume or directory reachable in the Finder.

By default, the files are shown as a pie chart: each circle represents one level of the directory hierarchy and the size of each section is proportional to the corresponding file size. When moving the mouse over a section, the name and size of the file are displayed.

You can freely navigate inside the graph: clicking on a directory makes it float to the center for a better view of its contents. If you want to see all file names and attributes, or some files are too small to see in the graph, just show the file list.

If you prefer to see all files at a glance, you can switch to the tree map.

By default, files are colored according to their position on the hue wheel. You can also colour them according to their creation or modification date: a warmer color indicates a recent file, while a cooler color an older one.

From the File or context menu you can show a file’s preview, show it in the Finder or move it directly to the bin, or just use the keyboard shortcut for even faster cleanup operations.

Disk Graph can export a scanned volume or directory as a snapshot file. A snapshot can be opened later as if it was a regular directory to see what it contained at that point in time. Multiple snapshots and directories can be opened as a so-called file sequence: an interactive animation that shows the evolution, or transition, between the selected snapshots and directories.

In the main window you can save your favourite volumes and directories and inspect them with one click.

I designed Disk Graph to be fun and easy to use. If you have any problem to report or a suggestion for a new feature, I’m always happy to help!
