If any link is down, then probably all files should be reuploaded, and it could be long and painful job with big files.
But if You use MapSource version than you could do with it whatever you want to do.
Unlock or not, export any part or complete, one mapset (or part) combined with other mapsets (or part), ..., whatever you can think of and all of it locked or unlocked (or combined).
All guides and tools (programs) to do it are here on forum, and if anyone have any questions about how to do it, we will help.
