I have the same question (of many).
As the above post, I see no result from the 'test' and no documentation.
By filename, would [ current\current.txt ] work in the folder path field for FTP current data export settings?
How does it handle multiple files then, overwriting them or adding some suffix/prefix? For the archive there's the '"FTP file settings' box, which seems to set - maybe? - the file naming, or is that just the data in the file?
Same question for 'FTP archive export settings',
with [ archive\archive.csv ] as the tested with no result setting (also tried at first just a folder name).
What I want to figure out on a broader scope is how to export VP2 data to my FTP to archive permanently long term (years, decades) and, if I can figure it out, use in a display program.
