How to send a batch file by email

Its a 'security' thing, and in this case, changing the extension is the easiest way to fix it. I did a few tests before and gmail at the very least checks 7zip, and zip files.

You need everyone in the company to run it - use a fileshare and share the link to it internally. You might also be able to upload it somewhere and get the link to the others. In this case getting creative is the best idea.

I have done it by simply double-zipping it, because Gmail does not unzip and checks recursively.

Archive it in .rar format, then .zip, or .tar.gz, or any other combination of two different archiving formats.

However, it may be a bit of work for some of your recipients to un-archive twice, so the other answers may prove more useful.

I don't know of any way you can do it without changing the file extension. The way I usually send .exe or any type of executables through email is by first zipping it, then changin the extension of the zip file (to something made up).
