Custom Export - Parent Directory

I would like an export to include the "parent directory".

I copy the standard MTE file, add: "%_parent_directory%"

using the same format as the other columns (other fields to export).

I keep corrupting the MTE file.

So, I just want to add the "parent directory" to the rest of the regular headings of "html_mp3tag"

Ok I'm a noob, what can I say

you could add a ..\ to the filename
$filename(..\myfile.html,utf-8)
