Hi,

1. "I have attached the file(s) above, which you requested." or "I have attached the requested file(s) above."
2. "Please download the file(s) from the attachment which is the quotation for machine SC100 model." or "Please download the attached file(s), which is the quotation for the machine SC100 model."

Cheers,
