Your files got dropped from Drop Box? Hmmm, if only there was some clue in the company name to dissuade a person from using their storage service. I know, it's nice to have a backup outside of a premises, but honestly, thumb drives in a safe deposit box are the way I rolled. I wouldn't take the chance of some country like China hacking Drop Box, and using all my SCREEN ZERO programs to rule the world. Oh the horror!
Hope you find it on an old back up. Too much good stuff was also lost when [abandoned, outdated and now likely malicious qb64 dot net website - don’t go there] went down, too.
