Why use email to send an attachment to someone when the attachment file can be transmitted using FTP?

FTP/Email Files

FTP is the protocol for exchanging files over the internet. FTP is most commonly used to download or upload files from or to an internet server. You will need an FTP application and you can download them: Fetch for Macintosh, and for Windows use WinZip or WS_FTP. (These applications usually have a 30-day trial period and then you can decide whether to purchase it or not). FTP is preferred when files get large because they will upload much faster than through email and FTP can handle much larger files.

Sending large attachments through email can be problematic. Some corporate email servers do not allow email attachments to guard against possible viruses, or an outgoing server may have a limit on the size of an attachment. Sometimes the limit of an attachment may be as low as a 2 mg file. Therefore, FTP may be the only option to sending your files electronically. FTP is also a much faster way to send files than through email.

If your files are especially large, 100 mg or more, it is recommended that you send a CD disk rather than sending files electronically.
