In columns, export scripts and format strings, \_FILENAME represents the base filename (no extension) as expected but in filter and actions, it represents the filename including extension i.e. what elsewhere is \_FILENAME\_EXT.

It's a feature and since \_FILENAME is not %\_filename%, I'd not consider this as a bug.

Well, if it is deliberate, I cannot see the point of two different fields having the same name and the same field having two different names.
Anyway, I suggest since \_FILENAME is undocumented in Help (as far as I can see), it would be useful to add a mention of this.

Thanks. And which topic is that? I've not found one that documents \_FILENAME.
