1. Connect the removable drive
Insert the thumb drive, flash drive, memory card, or external USB disk into the Windows PC.
Secure Portable Files on Older and Newer Windows PCs
Many USB drives still move between Windows 11, Windows 10, Windows 8, and Windows 7 computers. A drive may be used at home, in an office, in a classroom, at a client site, or on a shared service desk. Without protection, anyone who opens the drive can view ordinary files.
GiliSoft USB Encryption is designed for removable USB storage on Windows. It lets you create a secure area for confidential files while keeping a public area for files that do not need protection. This is useful when the same drive must carry both shareable and private data.
Recommended choice: use GiliSoft USB Encryption when the thumb drive or flash drive itself needs password-protected storage. Use USB Lock when the goal is blocking USB devices on a PC.

Keep public files available
