well.. i got the same problem.
i do want to have a zipscript and yes, it should create .missing files etc.
but i really want to prevent it from creating .bad files if i stop uploading a file.
it should just leave the file as it is, so that i can resume later.
i removed "OnUploadError = EXEC ..\scripts\ioBanana.exe uploadfailed"
from ioftpd.ini and restarted iopftpd.exe but it still creates the .bad files if i stop during the transfer.
something else that has to be done?
thanks a lot..
