Advanced EFS Data Recovery (AEFSDR) by Elcomsoft decrypts files protected with the Windows Encrypting File System (EFS) when standard access is blocked due to administrative errors, formatted disks, or deleted user profiles. The software functions by extracting encryption keys directly from the storage sector-by-sector and mapping them back to your locked files.
To use Advanced EFS Data Recovery effectively, follow these procedural steps: Prerequisites & Initialization
Admin Rights: You must launch the software with full Administrator privileges to allow direct, low-level disk access.
User Credentials: Have the original Windows account password (or previous passwords if it was reset) ready to drastically accelerate the on-the-fly decryption process. Step 1: Scan and Recover Encryption Keys
Before searching for individual files, the application must identify the master keys and self-signed certificates hidden on the storage media. Navigate to the EFS related files tab in the interface. Click the Scan for keys button on the main toolbar.
Select your local logical disks or partitions from the menu layout.
Wait for the processing to finish. Keys successfully decrypted will appear in green, while unusable or missing keys show up in red.
Click Backup data to export the found keys into a safe backup file so you do not have to perform a time-consuming sector scan again. Step 2: Target the Encrypted Files
Once the key framework is built, you need to import the locked files into the interface. Switch over to the File Tree tab. Locate your target directory in the left structural pane.
Right-click the folder and choose Scan for encrypted files (recursively) to automatically index all nested, locked contents.
Alternatively, click Select encrypted to import every single locked element detected on that partition directly into the processing queue. Step 3: Execute Decryption Advanced EFS Data Recovery | Elcomsoft Co.Ltd.
