export orders as csv files via mass action - where is the file?

Hi
i just tried to use the export csv feature as mass action.
the action should be triggered whenever an order is created.
i already managed to receive the mass action email with the csv file attached.

now, two problems/questions:
a) i had to enter a file-name in the file path to receive the csv-file via email.
is it possible to get a random name? especially related to question b, to get a csv file for every order on the server.
b) i am not able to find the csv-file in my server directory!?
i looked here: /media/com_hikashop/upload/ , but there is no csv file.
where can i find the csv-file?

thanks.

thanks for your reply,
i need to do more tests, but it seems to work.
i looked in the wrong path, because i found that in another hikashop thread ...
