Callback Technologies AES Drive provides a simple way to secure files by always keeping them encrypted on disk, while still allowing access to the decrypted versions through a mounted virtual drive. When the drive is mounted files are encrypted and decrypted transparently, allowing you to work with your files as if they were not encrypted. The full range of standard file operations are supported including create, read, update, and delete. No plaintext data ever touches the disk, all file data is stored encrypted and is only accessible while the drive is mounted.
