Repeated files


When I add a new folder some songs are repeated, even if the folder shows one file only. mp3tag shows twice some songs, showing in one of them tag and title info for example and nothing in the other. For those repeated files the Filename will start normally in one case and with ._ in the other. Why is that? Thank you

You are switching between IOS and Windows?

I can see not a single duplicated file. Some files have a number of characters in common, yet they differ in respect to the ._ at the beginning of the filename.
I can see nothing wrong because, obviously, these files are there.
Set your OS so that it displays hidden files as well.
