Dovoljno je samo da procitas Google-ovu poruku, nema tu sta mnogo da razmisljas, a poruka glasi:
"ffsav.sys is an executable file. For security reasons, Google does not allow you to send this type of file."
Dovoljno je da rename-ujes file da se ne zavrsava sa .sys extenzijom, i prosao bi, jer Google help kaze sledece:
"As a security measure to prevent potential viruses, Gmail does not allow users to receive executable files (such as files ending in .exe) that could contain damaging executable code."
Sto znaci da google gleda samo 'ending in .sys/exe/com' a ne gleda strukturu fajla.
