Cryptainer vs Folder Lock
Side-by-side comparison of features, pricing, ratings, and alternatives.
Cryptainer, made by Cypherix, is on-the-fly disk encryption software for Windows that creates virtual encrypted drives protected with 256-bit AES or 448-bit Blowfish encryption, letting users drag and drop files into a secure volume just like a normal disk. It supports encryption volumes from 1MB up to 10TB, works with any file type, and integrates directly into Windows Explorer, making it a lightweight option for individuals and small businesses who need local file and folder encryption without a subscription.
Folder Lock, from NewSoftwares.net, is a longstanding Windows file-security application that lets users lock, hide, and encrypt files and folders using AES 256-bit encryption. It creates password-protected encrypted lockers that can live on local drives as well as sync to cloud storage such as Dropbox, Google Drive, and OneDrive, and it can send encrypted files by email in a self-contained format that recipients can open without installing the program. Beyond encryption, Folder Lock includes a file shredder for permanently deleting sensitive files and can clear Windows temporary files, clipboard data, program tracks, and media history. The vendor states it has more than 55 million users, and pricing is a flat one-time license (around $39.95) rather than a recurring subscription, with a free version also available.
