Can someone help me please? I have a bunch of Whitburn pop files in the format: Year\_number - artist - title 1951\_001 - Johnny Ray & Four Lads - Cry 80 M (3.02).mp3 The current title tag is Cry. I would like to change that to 1951\_001 Cry I tried Convert but it adds the info after Cry in the filename. I also tried some actions, but couldn't figure out how to extraxt the year number part of the filename. ---

Try an action of the type "Guess value" Source: `$regexp(%_filename%,(.*?) -.*,$1) %title%` Target: %title% ---

If I create an action of type "Guess Value", I get prompted for source format and Guessing pattern. It does not prompt me for target. Thanks for the response, but I need more help. If I use an action of type "Replace Value" I think it would do what I want, but I can't figure out the correct syntax for the field, "Replace with". ---

> [@BobGee](#): > > Guessing pattern. It does not prompt me for target ok, there are 2 strings that you have to enter. One is the "Source format"(?) and the other one a format string as target. I have the German version so apparently the translation does not quite match. An action of the type "Replace" will not really work. ---

I figured out a 2-step conversion that works. 1, Convert filename to tag with format string %year% - %dummy% That puts the Year\_number from the filename into the year field. It overwrites whatever was in the year field, but I can live with that. 1. convert tag - tag with TITLE in the field and %year% %title% in the format string. Thanks for looking at my problem and making suggestions. ---

If you use a user-defined field like %myyear% instead of %year% in > [@BobGee](#): > > Convert filename to tag with format string %year% - %dummy% the you do not loose the original content of YEAR. The second step would have instead of > [@BobGee](#): > > %year% %title% %myyear% %title% Afterwards you may delete MYYEAR. But all this could be accomplished in just one step with the "Guess value" example. ---
