There are a few factors that play into how long a file recovery takes. The larger the size of the drive that is being scanned is, the longer it will take. Smaller drives (under 500Gb) may take anywhere from 30 minutes to a few hours to scan, larger drives (over 500Gb) may take multiple hours and even a day or two for Tb size drives. If a drive is damaged or corrupted, it will also add time to the overall recovery process. If the scan is progressing, do not stop the scan because you think it is taking too long for larger drives.
