Thanks again for your reply. I have tried using the files as a pair. But these are two different files. As mentioned in this link:
I have files of the types of JPG/MOV/MTS/MP4 shot with the same camera. Where can I submit these files?
These files were encrypted on 04/04/2019, when I try to use the decryptor, I got the following message:
File: H:\Studio 21\00003.MTS.refols
