One of my long-time rename expressions is no longer working.

The expression is:

Code: [Select]

if(IsEmpty([Featuring]),[Name],[Name] /(feat. [Featuring]/))
I have a custom list-type [Featuring] field where I add any featuring artists which are not the primary artist.
Where this field is populated, I like to append (feat. [Featuring]) to the end of the filename in rename operations.

Eg. Warren G - Regulate (feat. Nate Dogg).flac

Up until now I've used IsEmpty, but this doesn't seem to work anymore. The output always assumes the field is populated even when it's empty. The expression has been stored in my MC library for years now, but it's only recently stopped working for rename operations.

Now, for files where there is no 'Featuring' artist (ie [Featuring] is empty, MC is appending 'feat. Unknown Featuring' to the end of the filename.
It's worth noting when I test the same expression it works fine when in-line editing (panes view etc) - it's only not working when I use it in Rename/Move/Copy files.

Any ideas?

Try using:

  [Featuring,0]

instead of just:

  [Featuring]

Thanks MrC - I'll give it a try tonight. Does the rename/move tool handle expressions differently to the program  in general ?

PS what does the 0 do?

I always use a library expression field when I rename my files, both for files and folders. I've never had a problem.

Yes, and in several ways.  Here's the relevant one:

17.0.114 (3/26/2012)

1. Changed: When using list fields in Rename, Move, & Copy Files expressions, the full list can be retrieved by using 0 as the second field parameter (example: [Keywords, 0]).

Adding the 0 modifier to a field instructs MC to evaluate to the raw data, and not format it relative to the field's context.

So have I - but this only changed recently. It must be related to the change MrC mentioned in .114.

Thanks MrC. It works perfectly now. Thanks for clearing that up.
