Disk Graph for Mac OS is a nice app to check your Mac disk space and lets you find the files that occupy a major part of your disk space. The app is simple to run and has a beautiful interface.
The normal price of the app is $3.29, now for a limited time period the app is available free on Mac App Store.
Disk Graph allows you to visualize your disk as a responsive pie graph and find the files that take away your disk space. With its intuitive interface, locating big files has never been easier.
You can select any directory reachable in the Finder: it may be on your local machine, on an external drive or even on a remote server. Each circle in the resulting pie graph represents one level of the directory hierarchy and files inside a directory are sorted by size.
By moving the mouse over one of the colored sections, the name of the file and its size will appear. The file size is proportional to the section size. You can freely navigate inside the graph: clicking on a file will make it float to the center so that you have a better view of its contents.
The search field allows you to find a file inside the current directory. If you move the mouse over any of the search results, the corresponding file will light up in the graph so that you know where it is. With a click you can open that file, bringing it to the center.
From within the context menu, you can open a file in the Finder or move it to the trash. This way you can free space on your Mac directly from within the app.
In the main window, you can save your favorite directories and devices. When you launch the app, you can get access to them with one click.Disk Graph is designed to be fun and easy to use
