Open MiniTool Power Data Recovery on your computer. Under the Logical Drives section, choose the partition that contains lost data and click Scan.
If you are not sure which partition the lost data is in or the files in many partitions are lost, you can move on to the Devices tab and select to scan the entire disk.
After the scan, all files found from the scanned partition or device are listed by the path by default. You can find the missing files by unfolding each folder. Or, you can go to the Type section and choose to view files by file type.
In addition, Search and Filter are also helpful for you to quickly find the wanted files.
More importantly, to check whether the listed files are the wanted ones, you are allowed to preview them. Multiple types of files are supported to preview, such as videos (MKV, WEBM, MTS, 3GP, MP4, etc.), pictures (JPEG, JPG, JPE, BMP, etc.), documents (DOC, DOCX, etc.), audio, and more.
For video/audio files and most pictures, you can click the “Save” button in the preview window to save them one by one, or you can select the checkbox next to each desired file and click the “Save” button in the scan result window to restore the wanted files at once.
After clicking the Save button, you need to choose a storage path to save the required files. It is recommended not to save files to their original location to avoid overwriting deleted data.
