conversione catalogo da organizer 2021 a 2024. file multimedia replicati.

I don't know whether something has been lost in translation, but here are some possibilities of what you need to know.

• Before a conversion of the 2021 catalog takes place, a copy of the original catalog folder is made.  But the media files are not copied.  So the conversion did not duplicate any of your files.
• The catalog copy will be renamed with a -n suffix.  So, if your Elements 2021 catalog was named My Catalog, it will be renamed as My Catalog-1.  You can still use this catalog with Elements 2021 (and I would expect it to have all of the duplicate files such PhotoName-1.
• You can find and delete the duplicate files by performing a name file search:  Press Shift+Ctrl+K and enter -1 in the text box.  When you find what you think is a duplicate file, right-click on it and select Go to folder from the context menu.  This will show you all of the files in a particular folder and it will help you decide whether the file is a true duplicate (or whether it is a copy of a file that may have been edited).  If you are convinced that the folder contains duplicates, you can select and delete them from the Organizer catalog.  You also have the option to delete the duplicate files from your computer.
• Another possibility for confusion is if you have the folders panel in list view.  Make sure that the folders panel is in Tree View.

If you do in fact have true duplicate files in your catalog, you may want to find out why that is happening.   If you give us some more details, we might be able to offer some suggestions.
