Send exe file attachment via email

Free email providers such as G-mail, Yahoo! Mail, and others typically prohibit users to attach ‘.exe’ or executable files to emails and send/receive these emails through the Net. Security is the reason behind such regulation. Users are usually shown a message stating this, along with an error message saying ‘[xxx.exe] contains an executable file.’

Bots, Trojans, viruses, and worms are just some of the threats which anti-virus scanners try to obstruct. Email services utilize these to scan all emails and the associated attachments; thus, barring all types of executable files from transmission over the Internet.

Executable files that are not allowed in the sending and receiving of emails include:

  • .bat files;
  • .com files;
  • .dll files;
  • and .exe files.

‘Zipping’ or compressing these files with data archiving tools will still not allow the transmission of emails with these attachments. A few minor tweaks; however, will do the trick.

Change the file name of a single file. To send one executable file, modify its extension. ‘Xxx.exe’ can become ‘xxx.ex’, or simply ‘xxx’. Attach the recently renamed file to the email, and send. The attached file is now undetectable as an executable; thus, allowing it to be sent over the Internet through your email. Inform the recipient beforehand that the attachment in the email requires renaming. The file should be saved under the original file name, from ‘xxx.ex’ or ‘xxx’, back to ‘xxx.exe’.

Change the file name of a compressed file. These following tips are applicable to sending multiple executable files as attachments. Zip the files with any data archiving utility. Change the name of the archived file, ‘’ can become ‘xxx.zi’, or simply ‘xxx’. Attach the renamed file to the email, and send. The attached archived file cannot be read by email scanners as executable. It will be considered a single file, facilitating its transmission through email. The recipient should once again be informed that the attachment needs renaming (reverting to the original file name) after downloading.

Archive and encrypt. For those who wish to bypass file renaming, they may use encryption in archiving the file, appending a security password to it. The industry-standard algorithms utilized by encryption archiving tools shield the attachment. As the email scanners do not have the password, they will be unable to open the attached file. Remember to inform the recipient as to the password so that he or she can unzip and open the file.

Use ‘.rar’ archiving utilities, such as WinRar. E-mail scanners do not read ‘.rar’ compressed files as archive files, but treat these as single files, allowing email transmission. The recipient needs a ‘.rar’ tool to access the attachment.
