ohhhhh I see thanks!
I have another question, not sure I should start a new thread or not so just gonna ask here.
I have a `_DIRECTORY` Format Value:
`Z:\My Music\! %location%\$left(%artist%,1)\%artist%\'['%year%']' '['$left(%comment%,1)']' %artist% - %album%`
I was trying to figure it out on my own, but I just can't wrap my head around these syntax's. Anyway, how do I capitalize the letters? So these:
`$left(%artist%,1)` AND `$left(%comment%,1)`

Try
`$upper($left(%artist%,1))` and `$upper($left(%comment%,1))`
