PSE12 catalog moved

helpname22  wrote My pse12 catalogs were, and still are listed under C:> App data>roaming>org..... where they have been for a long time. At some point I followed some advice to make a copy of my catalog folder and I put it on an ext drive. Now it appears that pse12 is using the catalogs on that ext drive.  The same (named) cat folders are still listed on C but I'm not sure if they are up do date....I assume not. I have made several adds and deletes since the copy.

Keep in mind that a catalog folder can be copied or moved where you want (default location or 'custom' location) from your explorer or finder. That does not change anything to the information in the catalog. In your case, you now have two valid catalogs.

The other important thing to take into account is that anything that is changed from a catalog is ignored by the other.

You are right to wonder which of your two catalogs is up to date. I would check in each catalog by setting the sort order to 'import batch'. You'll see which of your catalogs is the newest one.

How do I get my cataogs back to the C:drive? app data is fine

The catalog manager has the option to move catalogs back to the default location on C: (Move button). To move from default to custom locations, you have to use the explorer or finder.
