The Locking Status dialog can opened by choosing File > Check Locking Status.... The dialog also opens before (batch) modifications are executed if not all selected files are writable.
If files are read-only (e.g., in a Shared Working Environment), or locked by other users, the Locking Status dialog shows these files in two lists. The file name and the versioning tool are displayed in both lists. In the Locked Files List, the name of the user who has checked out the file is also shown, followed by the file version number. Read-only files in shared working environments can be checked out, and files locked by other users can be unlocked or concurrently locked.
Pressing Ok closes the dialog and, if it was automatically started after a Change All command, the change process continues. If not all files are writable, you are warned by a dialog showing the non-writable files, and you can either continue or cancel the process.
Pressing the Cancel button aborts automatic check out and batch modification. No files are affected in any way.
