Move pictures from one catalog to an other?

OK.  There is a fairly easy solution. These instructions are for Windows.  I'm sure you can figure out the necessary changes if you are on a Mac.

1. Make a copy of your catalog folder using your OS folder copy command.  You can find the location of the folder by using the Help>System Info. dialog. (See screenshot below.) If you are using the default names and locations of your catalog folder, you should now have My Catalog and My Catalog(1) folders (using Windows File Explorer).  You can of course rename the folders to e.g. My Catalog (Photos) and My Catalog (Videos).
2. In File>Manage Catalogs dialog, open the My Catalog (Photos) catalog.
3. Press Ctrl+1.  This will take all videos out of the view.  (You can also use the toggle under the View>Media Type menu.)  You should now have only your video files in the Media grid.  If you have Audio or Project files in your catalog, you should hide them too if you want them to be in your photos catalog.
4. Press Ctrl+A to select them all.
5. Press Delete (but obviously do not check the box to remove the files which will pop up in a warning message).  You will now have a catalog that only contains your photos (and maybe your Project files if that's where you want to keep them.
6. Press Ctrl+1 and only your Photos will come back into view.
7. Next open the My Catalog (Videos) catalog and repeat the process by hiding the videos (Ctrl+2) and Ctrl+3 if you want your audio files to be hidden and remain in that catalog.  Delete all the photo files from the catalog.

You should now have two separate catalogs, one containing your photos and one containing your videos.

Added:  Michel types faster than I do.  😁

I want keep photos and videos in diferent catalog. Now they are all in same catalog. I know that my files are in harddick in their logations ant that catalog is only "map" for Elements.

To be clear, there is nothing to 'move'. Catalogs are independent lists and don't contain any media files, only links to the files on your computer. What is listed in a catalog is totally unknown from the other catalog list. You can include (register) the same files in both catalogs if you wish. you can delete a link in one of those catalogs without any change on the other catalog.

So, you can decide that a given media file should be deleted from the list of one catalog and 'import' that file in the second catalog. But we don't know if that is a correct answer because the real question is how to manage catalogs and choosing if there is a real need of having several catalogs (the best general rule is to have a single catalog).

Managing links in different catalogs has nothing to do with 'moving' files on your drives. Anyway, 'moving' is just an interface  metaphor for doing two things: 1 - copying from one location, 2 - deleting from the old location.

The short answer is that you can't.  But there are workarounds.  If you give us some more detail about what you are trying to do, perhaps we can make some suggestions.
