Title: Move, Copy, Rename - Truncate filenames in case they're too long?
Post by: amargolis on March 07, 2013, 05:24:56 pm

I'm reorganizing the folder structure in my library and getting errors due to filename/path being too long on tracks with really long "names." I'm sending all my files to:

Z:\Music Library\Album [Disc #]\[Track#]. [Name]

Ideally the disc # would only be added on multi disc albums, but it won't really bother me that much to have a "1" at the end of each folder name if that's not possible.

Thanks!

How do you want the name truncated?  Just chop off the last portion at some character limit?

Use this to conditionally include [Disc #]:

Z:\Music Library\[Album]/##/IfElse(!IsEmpty([Disc #],1), / [Disc #])\[Track #]. [Name]

To the rescue again, thanks man!

Yeah, fine to just truncate as you described, unless you know of a better way?

Is there any kind of glossary that could help me learn how you build these expressions? So I don't have to bug you all the time.  ;)

You're welcome.

You might want to create a view that tests the length of the entire path/filename, and perhaps modify those Names that are excessive.  You could use:

length(Z:\Music Library\[Album]/##/IfElse(!IsEmpty([Disc #],1), / [Disc #])\[Track #]. [Name])

as a pane column, and you'll see an ordered list of path lengths.

To fix your path, you might just truncate Name with Mid():

Z:\Music Library\[Album]/##/IfElse(!IsEmpty([Disc #],1), / [Disc #])\[Track #]. mid([Name],0,60)

where you change the 60 to the length you want.  You probably don't want to truncate before the path separator, as you might be chopping off a folder.

See the Expression Language (http://wiki.jriver.com/index.php/Media_Center_expression_language) wiki for the functions list and some examples.

Good idea, i'll do that to shorten the super long ones. Thanks.

When I use the rule you gave me, (Z:\Music Library\[Album]/##/IfElse(!IsEmpty([Disc #],1), / [Disc #])\[Track #]. [Name]) to create the file path, it's still adding a "1" to the end of album name folders even on single disc albums. I can live with it, but if there's an easy fix, I'll take it!

It will only add Disc # it if there is a value in Disc #.  For your single-disc albums, clear the [Disc #] field.
