Keep original last modified date of media file

Thanks for providing almost exactly the tool I was wishing for!

Here is a suggestion for an enhancement: It would be nice to set the media files last modified date to the creation or the actual last modification date.

Now, at a closer look, I see this happening for some, but not for all files. Might have to look a bit deeper. I'm on macOS.
