How to Send executable Files via Gmail
As a security measure to prevent potential viruses, Gmail does not allow users to receive executable files (such as files ending in .exe) that could contain damaging executable code. Gmail does not accept these types of files, even if they are sent in a zipped (.zip, .tar, .tgz, .taz, .z, .gz) format. Any message of this type sent to your Gmail account will be bounced back to the sender.
This is one of the best tricks i have evolved and it works fine and perfect. For example if you have a file called "Gre_Test.exe" .While sending it to your friend just rename it to "Gre_Test.exe.remove".
Or you can rename it this way . "Gre_Test.exe" be renamed to "Gre_Test.doc" . You can rename it to any file extension you want. Just be careful that the recipient renames it and then he will be able to use it.
When you rename you may get a warning saying …this ..you just say yes.

Then Send the file to the receipent.After the receipent recieve the file, ask them to rename the extension file with .remove and you have your original exe file back perfectly working .
Note :Renaming files can be tricky because windows hides the file extensions by default. Here's how to rename them:
- 1. Open explorer and browse to the file you want to rename
2. Click the Tools menu
3. Click Folder Options
4. Click View tab
5. Uncheck Hide extensions for known file types
6. Click OK
7. Now you should be able to see the extensions of your files.
8. Right-click on the file
9. Click Rename
10. Rename the file and change the ending. For example, Gre_Test.exe to Gre_Test.bak.
11. Now you can send it through gmail like any other attachment
12. The receiver of the email will need to rename it back so he/she/it can use the file correctly.
Enjoy.
