Examining & editing Time Machine backups

A modified version of the GrandPerspective disk sizing utility has surfaced which understands the file structure of Time Machine backups.

With this tool, you can scan Time Machine backups and immediately discern how much space it is really using.  Also, you can look for large files taking up unnecessary space.

To actually recover space, enter Time Machine and delete the unnecessary backups of your large files using the gear menubar item’s: “Delete Backup” and “Delete All Backups Of” commands.
