John,
I didn't mean to change filename but extension. With explorer settings it might be difficult to do. Use rename command

>>>Sometime we need to send files to a customer via email if the files are large we compress them using Winzip the problem is most of our customers don't have a utility to uncompress them or can't use it. I can't create a self extracting Zip file because the ISP's won't send any emails which contain EXE files. My question is, is there a way to send a compressed file that can self extract it's self that is not an EXE file?
