Click the Options menu icon (top RHS of the Files panel)
then Edit > Select Checked Out Files
I performed the select and check in. Shouldn't the symbol to
the right of my files change? Currently the lock is still showing.
The lck files are now gone from all but 2 sub-directories.
If the files are checked in on the remote server, the symbol in your local file panel will be a padlock - meaning that they are read only on your hard drive and available for someone else to check them out on the server.
If the files are checked out on the remote server (i.e. you're working on them), the symbol in your local file panel will be a green tick.
If your symbols are mixed up (suggesting DW is confused), I would check everything in again so DW can regain control of the .lck files on the server instead of you managing them manually. Then just check out the files you need to edit.
Thank you! Made my life a lot easier.
