Import not working in Photoshop Elements Organizer 2018 - help

Do I understand well? 

1 - You are browsing the left 'folders' panel on the left.

2 - You click on a subfolder to show the files in this subfolder which have already been imported in the current catalog. Keep in mind that If nothing has been imported yet, you can't do that because the subfolder is not shown in the left panel. More on this later...

3 - The downloader searches for media files not already imported AND checks that the files are valid. Now, either you are shown only the batch of the just imported photos. You may get a message saying that "no photos have been imported because they are already in the catalog or they are invalid or not supported". That is normal and 'as designed' to protect you from importing duplicates.

As stated in #2, in the left panel you won't see subfolders without any already imported media files (in the subfolder itself or the subfolders of this subfolder). To get the last message you have quoted, you must have been in one of two situations:

- you have tried to import from a subfolder shown in the folder tree with a blank icon, showing that no files are imported in that subfolder but its own subfolders do contain imported media files.

- you have right clicked on the master folder to 'display all subfolders'. That displays all the subfolders of that master folder, whether they have imported media or not.

The second message is a reminder of the usual way to 'import' files from files and folders when your attempt has been unsuccessful. The usual way imports all photos in the folder AND its subfolders when they are valid and not duplicates (already in the catalog).

When you get this message, you simply go back by clicking on the 'All media' button on the top horizontal menu or by clicking on another subfolder.

Tip:

If you see a blank icon for a folder in the left folders panel in the two situations above, choose 'reveal in explorer' to check what is really in the subfolder:

- no files in explorer

- already imported files (probably in different subfolders)

- unsupported files (see supported files format to check)

Also, to be sure that the files which are present and not imported are valid, so necessarily duplicates, you can create a temporary empty catalog and try to import them. If they import (are indexed, not copied) in the new dummy catalog, they are duplicates.

Duplicate files are files with the same date_taken and size in kilobytes, not necessarily the same name.
