Folder Lock review

Folder Lock 10 is a Windows encryption suite that goes wider than most tools here. Its core is the locker: an encrypted virtual drive using AES 256-bit encryption that grows as you add files, so you do not have to pick a size up front. Lockers can live on the desktop or inside Dropbox, Google Drive or OneDrive, and encrypted files sync to other devices including iPhone and Android. Sharing uses RSA 4096-bit public and private keys, so co-workers open shared files with their own passwords. Extras include portable lockers for USB drives, encrypted wallets and notes, file shredding, and a lock-and-hide mode that works even in Safe Mode. The free version caps the locker at 1 GB and syncs 2 devices; Pro costs $39.95 per year for unlimited locker size and 5 devices. It is a good fit if you want one Windows app for several privacy tasks, but free tools cover pure encryption.
