Sometimes someone only needs one file from your USB drive, or they need to borrow it for a quick transfer. The problem is that a normal USB drive can expose everything on it: old folders, photos, invoices, drafts, work documents, and personal backups.
This is the simplest free option when you have a spare drive and only need to share once. It reduces mistakes because there is nothing else on the drive to browse.
If you must use your regular USB drive, place the shared file in a clear folder such as "For John" or "For Meeting". Then check the drive before handing it over.
Hidden folders, vague names, and read-only files do not prevent someone from opening, searching, previewing, or copying other files on the drive.
GiliSoft USB Encryption fits the repeat-use situation: keep files meant for others in the public area, and keep private folders inside a password-protected secure area on the same USB drive.
