Saving PDF yields file with zero bytes
Yesterday I went online to retrieve a tax document from my mortgage banker. I downloaded the PDF file and saved it to my local drive. Next I tried to fax that file via an Internet fax service. I prepared the cover sheet and attached the PDF, then sent the fax. The recipient told me she'd gotten my cover page, but nothing else.
I assumed the problem lay with my Internet fax service, so I called their help line. During that call, to my great embarrassment, I discovered that the PDF file I'd tried to fax had no content. Windows Explorer showed a file name and showed that I'd created the file at the correct date and time, but the file size was zero!
I know now to make sure I really have some bytes to send, but the question remains: How and why does that happen?
