—Perforce
If you have locked a file, you should unlock it when you are done modifying it. Other users can modify the file while you have it locked, but they cannot submit a locked file until you unlock it. To help prevent file conflicts and make sure that everyone on your team has the most current version of the file, you should unlock and submit the file when you are finished working on it.
See Locking a File—Perforce for more information on locking files.
