No. USB Safeguard is 100% portable. Simply copy the executable to your USB drive once, and you can use it on any Windows computer by running it directly from the drive.

What happens if I forget my password?

Can I access my encrypted files on Mac or Linux?

USB Safeguard creates Windows-specific encryption. While macOS and Linux can mount NTFS drives, accessing encrypted partitions requires third-party compatibility tools not officially supported.

USB Safeguard is completely free freeware. There are no registration fees, subscription costs, or hidden charges. The developer accepts voluntary donations to support development.

What is the maximum USB drive size USB Safeguard supports?

USB Safeguard supports protecting volumes up to 16 terabytes, making it suitable for modern large-capacity external hard drives and enterprise storage devices.

Will encryption slow down my USB drive?

Encryption may reduce USB drive speeds by 10-15% depending on your USB version and system specifications. NTFS-formatted drives generally perform better than FAT32.
