A little advice,take the oldest ones, and overwrite with newer and so on ...... at one point after you come to the end you will have x files with x versions, and all missing from the most recent. Delete at hand older versions that have different versions and you are at day with all. Do this for each brand in part.

It's much quicker to take the latest one and then copy older with option to skip files if found. In that case, you wouldn't have to overwrite most of the files for x times.

But as I mentioned, there are files with exactly the same name but have small differences in file size. I do think they contain the same flash file but are different only in compile date or something like that...
