Actually, it looks like the file structure is corrupted. The first thing I suggest it learn to use the cloud. It will make your data available on all your devices. Some services will allow you to track versions of documents and permit collaboration if you are on a team project.
I encrypt all my removable media and I do not trust backups to any single place.
Flash drives have a finite life. Most will not give you a nice warning they are going bad.
Destroy the chip before disposing of it. Data you deleted may be retrievable and in today's digital world, it can come back to haunt when you run for political office down the road.
