reformating YEAR field

Hi, I have a bunch of old MP3 files that for whatever reason have the YEAR field formatted like this:

xxxx\\xxxx

Is there an easy way to automatically cut off everything after and including the '\\' so I can get a simple year?

for example

2016\\2016 -> 2016

Thank you in advance!

The \\ is MP3tag's representation of a multi-value field: you have at least 2 fields of the type YEAR in the files.

There are action to either merge the fields to one field (use a different separator than \\) or to delete all duplicate fields.

Or you have a look at the extended tags dialogue (Alt-T) and see the fields there and decide which field to delete.

Removing duplicate field action did the trick --- thank you again!
