Locking a File—Subversion
When you are working, you may want to lock the files you have modified. Locking a file does not prevent other users from modifying the file. However, no one else can commit a file that you have locked unless they steal the lock from you or until you remove the lock.
You can steal a lock from another user if you need to commit the locked file while they are working on it. Likewise, another user can steal a lock on a file you have locked.
For more information see the Flare online Help.

Note: You cannot lock files with Rename status.
Note: Subversion will automatically lock a modified file when saving changes (if it is not already locked) if you selected the option to automatically check out files from source control when saving them. Because there is not a "checked out" status for Subversion files, these files will be marked as modified and can be committed.
