Creating new catalog corrupts original catalog
I am having trouble with the Catalog in PSE 2018. I have a main catalog with most of my stuff in it including Albums, ratings and tags. For a special project I created another catalog and imported all the pictures from a different folder than the Pictures folder. When I went back to my original catalog, there were no pictures so I imported them back in again from the Pictures folder. However all the Albums are gone and so are many (but not all) of the tags and ratings. I am running Windows 10 Professional with all the pictures (and other data) moved to the 😧 drive using sysgen during the windows install. The Catalogs seem to be stored in C:\Programdata\Adobe\Elements Organizer\Catalogs. I have backups of all the stuff in my user directory from the 😧 drive but the Windows File History doesn't appear to back up the Programdata on C so I have no current backup of the catalogs.
Here are my questions:
Am I correct about the location of the Catalogs. There are appear to be other copies of catalogs elsewhere on the system but none that are anywhere near current.
What did I do wrong? I have had ongoing problems with the Catalog and have had to redo Albums , tags and ratings before.
Where are the following stored:
Tags (It appears they are stored in the individual file metadata but why are many of them gone)
Albums
Hope you have some insight into how things are going wrong.
Thanks.
