Currently, FileFolder() works backwards up the tree.

So if your expression is: filefolder(c:\some\other\folder\a\, 2)
It will return "other".
 
However I have some paths where the number of sub-directories is variable.
For example "C:\Video\TV\Series\Season 1\"
If I use FileFolder(,1) that will return "Series"
 
But some TV shows only have a single season, so I have omitted the "Season 1" folder.
In this case the path is "C:\Video\TV\Series\" and FileFolder(,1) will return "TV" instead.
 
Is there any way that we could evaluate from the left rather than the right?
Perhaps using negative values?
 
Then FileFolder(,-3) would return "Series" for both paths. (there's a reason I want to evaluate the path rather than the series tag - this is just an example)

That woul be cool. I'd prefer a new mode to the negative thing.

So, +1.

But, you can make your own version of filefolder() with the regular string parsing functions and listbuild() with delimit on \.  That's what we used to do before there was a built in filefolder() expression.

It was hard to go backwards before, but reasonably straightforward to read from left to right.  MrC has posted instructions before.

You're right, that's easy enough to do with:
 
ListItem([Filename, 0], 2, /\)
 
I suppose there's no need for any changes or new functions, since it's basic enough that anyone trying to write an expression should be able to figure it out.
 
Just didn't occur to me to use that.
 
So now I can distinguish between TV shows and Downloads, since videos downloaded from YouTube via MC end up with a [Media Sub Type] of "TV Show" but are in the \Downloads\ directory rather than \TV\

Yeah. ListItem.  I couldn't remember the exact details off the top of my head.
