When a file is deleted, there will be a free data space. You still have a chance to scan your lost data and recover it. But if you keep entering data into the same disk, the system will store new data in any free space randomly.
Once the free space is filled up with new data, the original data is covered and erased forever. It is impossible for the data recovery software to scan the original data, let alone recover it.
Please save all recovered data to a safe storage device to avoid data loss again.
