3. The File Browser : Revert: Undoing Changes : Revert to Most Recent Version

Revert to Most Recent Version
(This command is enabled only in a workspace, and only for file elements with (modified) status. Link and directory elements cannot have (modified) status.)
This command replaces (by invoking the Populate command) each selected  file with the most recent version you created with Keep. (This command does not undo any namespace changes you made with Rename or with Cut-and-Paste.) The selected elements remain active in the workspace. That is, they are not removed from the workspace's default group. The (modified) status of the elements changes to (kept).
Use this command when you have saved one or more intermediate versions of the files, and you want to discard further changes you have made since a Keep.
If you have modified a file but not yet performed a Keep on it, this command works like the Revert to Basis.
