I used WinRAR version 3.00 beta 5. I used WinRAR because I could divide the file up into managable chunks. My website balks at downloads over 5MB in size. It will let me upload a huge file, just not let anyone download it. Since the Zip for the CR2 would weigh in at 25MB easy, I went the WinRAR route. Sorry this has been such a hassle for everyone. Any solutions would be greatly appreciated. I also tried decoding the files and didnt run up against the CRC error. Thanks, Dave
