Your the files are ghosted in the background. So they're deleted, but

the file isn't completed gone. You can do it in command line, but that's too complex to go into

Best way to make sure if you want them gone, is to copy all the files onto your pc drive. Once backed up, go to the usb flash drive and format it

Should be as easy as right clicking on the "removeable disc" and going "format".

That will delete everything as it reformats the flash drive. Then you can copy back the files you want on it

Otherwise those images you can't get rid of will be there forever

You could create a junk folder on the flash drive, and put them in there if it irritates you seeing them !
