Scans of individual folders are faster than those of the whole file system, so they may be more efficient if you want information only about a specific part of your file system.
Press the button in the top-right of the main window and select Scan Folder….
A file chooser dialog will open. Choose the folder which you want to scan.
Click Open to start the scan.
The folder which you just scanned will now be added to your list of Devices and locations. If the folder is renamed or deleted, it will be removed from the list when you next restart Disk Usage Analyzer.
