Hi Peter, Thank You for your quick response. I think I've discovered something that may help you figure this problem out.
I re-uploaded a few folders using WebDAV and checked the files that failed for anything in common and what I found is that when the files were named the File Name contained an "&" Symbol and by removing that Symbol and using the word "AND" instead the files were able to be uploaded just fine. I'm not sure if this Error would appear if any other non-alpanumeric character was used, but I can not upload ANY file that has the "&" Symbol in the file name until I rename the file.
Please let me know what you think. Thanks again
