i'm on an MC tear, so pardon all the questions lately
i have a lot of files where i've used [keywords] to alter the viewing. it of course works great
but now, i want to move files around physically...i have hundreds of thousands of work documents/photos that i have used keywords to dictate the viewing (i.e. by project, client, etc.)
i would really like to use the keywords to choose where they go....the problem is, some have say 10 keywords while others have 1 keyword, so using listitem doesn't seem to work, as if i choose listitem([keywords],1) it always returns null (the files go to the specified parent folder).
i should specify, that when using a listitem expression for a pane view it always works fine, just not in the move files dialog. i've been reading about 0 as empty and all that, but there are no files without any keywords therefore no blanks
is there an expression way around this?
thanks
edit: there's clearly something going on that's different about the R,M&C file dialog than from the regular expression pane. i can make this work six ways from sunday in panes, but it never, ever works in the dialog.

The Rename tool uses the Display representation of a field (not the Raw version). This happens so that fields such as [Artist] which might be used as a path component like:
...\[Artist]\[Album]\...
do not disappear when the artist value is empty, because you'd end up with:
...\\[Album]\...
and this is path you probably don't want. Read about Field Values (http://wiki.jriver.com/index.php/Expression_Language#Field_Values).
Since [Keywords] is a list type field, the Rename tool deals with it in its Display form. And in its display form, there is only a single string - all your keywords joined by "; ". So, you want to use the raw form [keywords,0] in your ListItem() when the expression is being evaluated by the Rename tool. This is explained in Field Values: Empty, 0, and 1 (http://wiki.jriver.com/index.php/Expression_Language#Field_Values:_Empty.2C_0.2C_and_1).
