Why do I get 3 sets of photo files when I transfer 3 catalogs.

Question

Transferred 3 catalogs from old computer, PSE 9, to new computer, PSE 11.  Result is 3 sets of photo files, all different trees.  Did this previously, then put all files in one place, reconnected one catalog and the tags were all messed up.  Wrong tag with the pictures, not acceptable!  I have about 6000 pictures in files by date.  Many files have pictures sorted into more than one catalog.  Reconnecting also brought the wrong pictures into the catalogs.  Had to delete everything and start over.  How do I end up with all picture files in one place - Pictures - and also have 3 catalogs accessing the correct file.  It worked great in PSE 9!

You should have three different folders named "Library". They are
<~/Library>, or the Library folder in your Home folder (aka, Library folder from user domain)
</Library>, or the Library folder at the root level of your startup disk (aka, Library folder from local domain)
</System/Library>, or the Library folder in the System folder (aka, Library folder from system domain)
And under no circumstances should you even dream of deleting any one of them.
Should this dream ever occur, you need to get cured by reading a basic book about Macs, eg, David Pogue's "Missing Manual…".
