What Organizer file to copy?

I recently purchased a new computer and was able to put PS Elements 2021 on it.  However, the old computer has all the files.

I need to copy or import the Organizer file with all my photos to the new computer but I don't know which of the many files in the Organizer is the correct one to copy.

Thanks for any help.

You have to follow the following procedure:

This creates a backup folder on an external drive, which will be restored from the new computer resulting in:

- a restore of all the folder trees of your media files

- a restore of the catalog (the database)

- and an update of each item in the catalog to register the new location in the new drive.
