I've exported an mp4 file to my desktop. Received a message that the export was complete. But can't open the file in Quicktime. The thumbnail of the file will play though (not very useful). Now can't even delete the file from the desktop
Using iMovie 10.1.13, OS 10.15.1
MacBook Pro
Thank you Rich. Discovered late this morning a simple reboot fixed the issue. Movie now plays and was able to delete the extra files off the desktop. To answer your question about deleting in case it happens to someone else, I could drag it into trash, get the audible alert, but the trash can remained empty, and the files remained on the desktop. Not just my movie, but other files I was experimenting with I no longer needed. Anyway, thanks for the response.

Your Quicktime version must be at least Quicktime 10, not Quicktime 7, to work with Catalina. So check out which version your are using.
As for deleting a movie from your desktop, are you saying that you cannot drag it into the trash and empty the trash? If so, try booting up in Safe Mode (see Finder Help menu for instructions) and, after everything loads, reboot in normal mode. See if that cures it.
