Hi,
Ludek will not be available for this week, but here is explanation.
There is no unfortunately 1 click solution as MM uses HDD Partition serial number to identify where the files reside and not file paths.
Before we go to solution, rule number one is ALWAYS have backup of MM5 library
see default locations before you do anything with it.
Now the solution:
As you mirrored your music to Jump drive I guess you already have MM5 installed on laptop?
If yes please do the following:
1. Copy desktop MM5.DB to Laptop
2. As your files are not on desktop PC, but on Jump Drive do not scan Jump Drive, but use use file -> Locate moved missing tracks to pair tracks from desktop (they will not be playable on laptop and their properties will have no drive letter) with mirrored ones on Jump drive
3. Do the playlist rebuild
4. Once you go back home copy laptop MM5.DB to desktop (Unless you already have, do not forget to make backup of desktop MM5.DB just in case before overwrite it with one from laptop)
5. DO NOT plugin Jump drive as you will not use those files but local ones
6. Use file -> Locate moved missing tracks to pair tracks back to local Desktop copies.
7. Rebuild of Playlists should be preserved
If not, you have done something wrong (I have done that at least 300 times over the years without any problems)
Only downside is that each time you want to do changes to desktop MM5.DB you need to repeat the process and make sure that mirrored files are updated on Jump drive.
If you have any questions please let me know.
