Removing large files from Time Machine?

"To delete files from a Time Machine backup:

Open Time Machine when you have the Finder window displaying those files
Select the items you wish to remove the backup(s) (you can select multiples using shift to select a section or command to select just one at a time)
On the action button (what looks like a gear) in the toolbar choose Remove From All Backups... or just Remove from Backup if you only wish to remove the one instance of the file.
You will be prompted for your administrator password and then you're done."
