    Disk overview, scanning

    The big picture

    Upon launch, DaisyDisk displays the list of all volumes mounted on your Mac with your startup disk at the top:

    Disk overview

    You can easily tell which disks are running out of free space by taking a brief look at disk usage gauges. Green color means at least half of your disk is empty, red is often a clear call to action. The only number below the gauge tells you how much space is left and pointing it also reveals the amount of used space.

    Scanning

    To find out what exactly takes up your disk space you need to scan the disk first.

    You can scan whole disks or individual folders. In the latter case scanning takes less time due to a smaller number of files.

    To scan a disk click the Scan button next to the gauge or simply drag and drop the disk from Finder to DaisyDisk’s window or Dock icon. Folders can be scanned by clicking the Scan Folder… button or dragging and dropping them from Finder.

    Scan process usually takes 1 to 5 minutes mostly depending on the number of files and folders on your disk and disk type. Network shares, virtual disks or Time Machine backups often take longer to scan.

    If you frequently scan a folder, click on its icon to star it. Starred folders remain pinned to the list of disks after you restart the application.
