Choose GiliSoft USB Encryption when you want a practical removable-drive workflow with a secure encrypted area on portable media. Choose BitLocker when your main goal is Windows full-drive encryption.
1. You mainly want to protect files carried on removable media.
2. You want a secure area plus a public area on the same portable drive.
3. You need a simpler portable-storage workflow for office, travel, or shared-PC use.
You want Windows full-drive encryption rather than a removable-media-focused product workflow.
