Remo Duplicate Photos Remover has two types of scans i.e. exact scan and similar scan.
Exact scan - The exact scan is a normal and default scan. It scans for the photo with same size, pixels, and resolution. The exact scan is a quick scan and completes by displaying the photo with same structure i.e. copy of the same photo.Similar scan – The similar scan takes longer than an exact scan as it will scan deep on sectors for checking duplicate photos and same photos with a slight difference. The similar scan will produce more photos in the results compared to exact scan.
