Don't override CSV on export
Is it possible to perform an export to a CSV File without overriding the Data, which is already in this File?
Means the data which I want to export should be added at the end of my file "*.csv"
You can use a plugin (MBS, Troi, others) to append content to file - or You can read the csv file first into a FileMaker table, add the new conten to that table as well - and create a new export using the same filename.
A Plugin might be easier
