Encrypting File System (EFS) is a built-in security feature in Windows Pro, Enterprise, and Education editions. It allows users to encrypt files so that only the specific user account that encrypted them can read them. EFS is invisible while you work, but it becomes a nightmare if you reinstall Windows, disable a user account, or try to access those files on a different computer.
Instead of fighting Windows permissions, you can use Wise Folder Hider to decrypt EFS files by using its built-in EFS decryption assistant. Here is the step-by-step guide to take control of your EFS-locked files using Wise Folder Hider.
Step-by-Step: Decrypt Files Using Wise Folder Hider
Step 1. Launch Wise Folder Hider
Run Wise Folder Hider as Administrator, and navigate to the EFS Decrypt section from the top toolbar.
Step 2. Scan for Encrypted Files
Click Scan to let the tool detect and list files protected by EFS.
Step 3. Import Certificate (if needed)
If no valid key is found, click Import Certificate. Select your backup .PFX file on the disk, and enter the certificate password.
Step 4. Decrypt the Files
Right-click the target file and select Decrypt selected.
For multiple files and folders, check the boxes for them, and click Decrypt.
Wait for the process to complete, then the files should return to normal in Windows Explorer.
Final Thoughts
The EFS Decryption Assistant in Wise Folder Hider simplifies what would otherwise be a complex recovery process. While it cannot override Windows security, it provides a structured way to locate certificates, import keys, and decrypt files efficiently.
