Patti When I get that zero length error msg, it almost always is a result of not specifying the correct path to the file on my hard drive. I place all of my files for upload in a folder I call \bs. So to copy a book with the file name hotdog.rtf, in the box for the file name, I enter c:\bs\hotdog.rtf where "c:" is the letter of my hardrive, \bs is the folder / directory where the book resides, and hotdog.rtf is the name of the book file itself. When I forget to place the book properly, or I fail to specify the complete path to the book file, I, bingo, get that error msg.
