Using the software is extraordinarily intuitive, even for non-technical users.

Step 1: Download and Install Download the 3.1.6.2 installer from the official Tenorshare website. Avoid third-party mirrors to prevent malware risks. Run the installer and follow the on-screen prompts.

Step 2: Launch and Select a Module Upon opening, you will see two main tabs: “File Repair” and “Advanced Video Repair.” Choose your required module.

Step 3: Add Corrupted Files Click “Add” or drag and drop your corrupted files into the interface. For documents, you can add PDFs, Word, Excel, or PPT files. For videos, add .MP4, .MOV, etc.

Step 4: (Optional for Video) Add a Sample File If repairing a severely damaged video, you will be prompted to add a healthy sample file recorded by the same camera/drone. This step is crucial for high success rates.

Step 5: Start Repair Click the “Repair” button. The software will analyze the file structure, reconstruct missing headers, and fix the damage. Progress bars show real-time status.

Step 6: Preview and Export Once repaired, click “Preview” to verify the content. If satisfied, click “Export All” and choose a save location (ideally a different drive to avoid overwriting).

Download the software from the official Tenorshare website. Install it on your computer (do not install it on the same drive where your corrupted files reside if possible, to avoid overwriting data, though this is less critical for repair than for recovery).
