You'll find the option to upload in binary format (1s & 0s) in your FTP software.

Your FTP client can transfer files in two modes - Text (sometimes called ASCII) and Binary.

Most FTP clients use "Auto" mode and make the determination regarding transfer type on their own. In most cases this works fine.

Occasionally you need to manually set the transfer type, the instructions in your FTP program will tell you how to do this. I may also be able to instruct you if you let me know which FTP program you are using.

In every ftp program I've run across, the DEFAULT is binary. So you should be farily safe if you need to upload in binary and your binary file has got a non-text extension. (Example - NOT .php or .txt or .html or such - those are usually pre-programmed as text/ascii)

Also every ftp program I've run across also has a way to select exactly how a file is uploaded. So if you are worried - just tell it to upload in binary. (Talk to Bill, since he has offered. )

worse case, open a command prompt and:
cd /dir/with/file
ftp ftp.host.com
user
password
cd /dest/dir
bin
put file.name file.name

I had this exact question about a week ago....and Bill pointed me in the right direction.

BTW, did you get my PM Bill?
