What is the difference between “Rollback…” and “Back Out Submitted Changelist #####” in Perforce P4V

Question

I want to reverse the changes from one of my checkins. In the right-click context menu of the particular changelist, there are these two options:

• Rollback...

Answer 1

Rollback... will prompt you to select a folder to rollback, ie, it will work on specific folders, and you can rollback to labels or changlists or dates. Back out works on the files in specific changelists.
