What is GrandPerspective?

GrandPerspective is a small utility app for Mac that shows graphically the disk usage within a file system. It uses so-called tree maps for visualization. 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 arbitrary.

When the app starts it shows a Welcome window. Here you can select a folder that has been scanned before by double-clicking it in the list of recently scanned folders. Alternatively, you can select another folder by clicking Scan Other Folder. Select folder to scan to determine the size of all files in it.

The software offers hight configurable display of views. From GrandPerspective settings, you can select color mapping schemes and color files by their name, extension, file type, parent folder, top folder, level in the folder hierarchy, creation time, modification time, or last access time.
