If what you used Disk Drill for was finding what's taking up space and clearing duplicates, Diskaroo is built for exactly that job. It maps a drive as a treemap or a sunburst, finds exact duplicates by content in whatever you scanned, and moves what you clear to the Trash, where you can still get it back. It runs on Mac, Windows and Linux, and it's free: sign in with a free Bravely Account, map your first folder, then claim Diskaroo Pro in the app, free, for life. For getting deleted files back, use Disk Drill.
Is Diskaroo a free Disk Drill? For the cleanup side, yes: it maps disk space and finds exact duplicates on Mac, Windows and Linux.
