Hi Jeffrey
Rest Assured, whether a file is hidden or not has absolutely no affect on the way the operating system treats that file, it is no more likely to be deleted or become corrupted just because the Hidden Attribute has been set on that file, you have nothing to worry about
Please be aware, that another user just has to turn on Hidden Items on the View Tab in File Explorer to be able to see your files
Something you may be interested in is the totally free VeraCrypt Portable
That can be used to encrypt the contents of a Flash drive for use on any PC . . .
