Hence, why you are supposed to delete the file(s) when not being actively used for an import/export (which is the only reason why there should be files in the import directory in the first place).
I only say this because not everyone is aware that the file should be there
only during this procedure.
(I don't think it's in the admin manual to delete the files.)
Surely, if it is not immediately apparent to me (and granted I may
not be the most intelligent of people...) then it may not be immediately apparent to others.
They may (for instance) carry out the procedure - download the files - and then not even give a second thought to deleting the files from the server.
I'm not looking to cause trouble mate, I just want to help people who may leave themselves in a vulnerable position.
