Win11 /c_drive MusicBeeLibrary.mbl locations? And other Q's

[aaeiouy]

This question refers to a "vanilla" win11 MusicBee install (no roaming, no last.fm, nothing complicated), intending only to connect playlists to tracks on the local (c:\) drive.
It is perhaps complicated in that the MusicBee folder is backed up on Dropbox, but the folder with tracks (i.e. mp3s) is not--just on the c drive. Complicated because changing a MusicBeeLibrary.mbl file on computer, but connected to dropbox, propagates that .mbl file to all computers using the same dropbox. So, you can't rely on different computers as backups. Wished I had realized that...

I catastrophically messed up the migration of Musicbee from one laptop to another and am trying to recover. In the process, I made several copies of MusicBee folders from various computers--hoping to be able to revert to pre-migration.

I want the playlists to connect to the tracks. I really want the play counts to migrate as well.
Questions:
1. How, from inside MusicBee, do you known the location of the current MusicBeeLibrary.mbl file?
2. If you have multiple differently named root MusicBee folders, all containing MusicBeeLibrary.mbl's, if you click one one of them, does MusicBee only use files in that folder, or are other locations also involved, e.g. AppData\local\MusicBee\, or c:\user\xxx\Music\MusicBee,that could affect linkage, play count problems?
3. Where are the play counts anyway?
4. Steven once said try deleting the MusicBeeLibrary.pfidx, but what does that actually do?
5. In Preferences>Library>the Library Playlists box says only "\Playlists", i.e. no complete path. If it did have a path, I'd know the answer to 1)

Sorry to ask 5 questions in one post, and thanks in advance to anyone that can help. Have tried cruising the forum and wiki and google, but can't find a detailed description of "where MusicBee stores its brain."

1. file> library> open library: you will see the path to the (checked - current) library after library name.
2. other locations will be involved, but what settings, which may be stored in other locations, do you mean exactly?
3. in the .mbl (library) file.
5. maybe "Playlists\" rather than "\Playlists"?  it's the path relative to the library folder (the folder where .mbl file is stored).

Thanks Baroda!
re 2), just those involved in linking tracks to playlists.

Sorry to misspell your name, Boroda.

all settings, which relate to current library including playlists (i.e. edit> prefs> library) are stored in library folder. but you will have to relink music files if their folder structure is different from old folder structure (referred by playlists/library). to relink music files, do the following on new pc/restored library: file> library> relink music file paths.
