What does that mean? When you search for an image and find it, and you right-click on it and select “open file location,” what happens? Nothing opens?
If the file is 64K, it could be that all you have is a thumbnail.
And you never answered my other question. When you right-click on the image folder on the thumb drive, and choose “Properties,” what does it say? It should list the folder size (how much data is contained in that folder) as well as the number of files and folders contained.
Is it possible that the thumb drive is honked up somehow and the files got corrupted in the transfer? I would try just transferring a single image from the computer to the drive and see what happens with that.
It opens to a file marked Patterns.
There is nothing on the thumb drive now.
I transferred, not copied.
The information should actually still be there (assuming you haven’t overwritten the thumb drive), so even if you can’t find it on the computer, you should be able to recover it using recovery software. (Deleting files does not usually actually erase them until they are overwritten with new data.) But it sure as heck sounds like you have the files on the computer (or possibly cloud) somewhere.
Huzzah!
I FOUND THEM!

Joey P** and Mithras–that contain folder showed me there was a weird kind of file-in-a-file!
Securing them, by transfering them to the top level of the Library, where I have already verified they arte arriving!
I’d take you all out for Pizza, but I don’t live in Chicago!
That’s ok. I’ll settle for an ebeer.

Okay, that leads to wondering how you backed them up? Drag and drop, or use some backup program? If a backup program, it could store everything in a single compressed archive.
Select, then Move to.
From now on just copy and paste. Once you are satisfied the job was done then you can delete the files. That way you have two copies in case one failed.
