How to Find Duplicate .MOS, .MRW & .ORF Raw Photos in Windows


RAW files and image formats are hard to maintain. If you are a professional photographer or know any, you know how typical it is to segregate images based on them. Not only this, but finding duplicate MOS, ORF, and MRW images other than the .JPG format is also not easy.

Luckily, there are ways to find duplicate photos with .MOS, .MRW, and .ORF RAW file extensions, and this blog will explain them.

For those who need complete access to their image files, saving them in RAW formats especially .MOS, .MRW, &.ORF is helpful. These formats allow users to open, edit, and tune an image to its maximum capacity.

However, nothing seems to work right when these pictures are filed with duplicates. There are several ways to deal with this problem, but using a duplicate image cleaner is the most accurate and less time-consuming way.

Ways To Find Duplicate .MOS, .MRW & ORF RAW Photos

While dealing with an image collection, you can open them in Photo Viewer and glance at them. However, the same is not the case with .MOS, .MRW, and .ORF, RAW format pictures. To open these files, you need professional-grade picture-viewing software. Moreover, compared to JPG these files are hefty. Where a normal JPG ranges between 100 KB to 25 MB, the raw picture sizes start from 25MB and can go beyond 100 MB. This is why keeping duplicate files in such formats should be avoided, as it can take up a lot of space.
