@KHS: you might try
- reading the manual
- using the search function of the forum
- making a backup of your MSP data and experiment

A tad snarky, no?

1 - I ALWAYS read the manual first. It mentions nothing about Swapping for 1 file to change it for all. It also mentions nothing about the name having to be the same. It suggests instead that I can mark all the songs and then Swap, which does NOT work. Mike's reply makes that clear. One SHOULD be able to mark multiple files that rely on one .PDF and swap that out in one simple maneuver--and the .PDF filename of the new file should not need to match the old. The program should work for me, not the other way around.

2 - I DID search on several different versions of "swap" and "multiple" files and nothing relevant was found.

3 - That's what I'm usually stuck with doing and I never apply new techniques to my real working library--only to a separate installation on another computer. I should not have to outsmart the program every time to get simple things done. Eventually, it will outsmart me and I'll do something that appears to work and it will be too late to restore from a backup when I realize the glitch.

My point (still valid) is that after doing all those things, it should be FAR more intuitive and, at the very least, procedures outlined in the manual should work. In this case, it does not.
