Advanced EFS Data Recovery is an effective, yet relatively easy to use tool for recovering data encrypted by the built-in ESF mechanism in Windows. Encrypting File System (abbreviated to ESF) is a function for encrypting data stored on a computer hard drive, which is available in various editions of Windows, starting from version 2000. It was created to allow the user to easily encrypt selected files and folders (this operation is limited to selecting the appropriate option in properties), as well as conveniently manage access to them by other users.

Despite its many undeniable advantages, the ESF unfortunately also has drawbacks. The data encrypted using it is related to the user account from which encryption took place. Problems with access to ESF-protected data start if we inadvertently delete a user account or if the system crashes and we do not have the appropriate keys that would allow us to access them after reinstalling Windows.

The solution to these situations is Advanced EFS Data Recovery, which allows you to decrypt protected files and folders, and supports all versions of Windows where ESF is available. The tool supports DESX/3DE3/AES encryption methods, allows you to search for encrypted data on the drive, scan for encryption keys at file or sector level and analyze deleted data. Advanced EFS Data Recovery offers two types of graphical interfaces, for beginners and experts.

The programme is also capable of backing up ESF-relevant keys and restoring them where necessary.
