Email Tools

If you have the ability to install software on your work computer, by far the easiest way to move files back and forth between your home and work computer would be a file synchronizing product like DropBox. But if you don’t, what’s the best way to move a relatively large file between two remote computers? For small files, email is usually the answer, and for users of Gmail that expands to files of up to 25 MB in size. But with what can often be a big catch: Gmail won’t allow you to transfer executable files, even if they are inside a zip archive.

However, if you’re simply wanting to move a file between computers, you can exploit the fact that Gmail doesn’t actually scan a file to see if it is an executable until you actually try to send the email containing the file. This means that you are free to attach any file up to 25 MB in size to an email in Gmail, as long as you don’t send it. You can then log into your Gmail on another computer, and download the attached file, without ever running into the executable file restriction.

Of course, the other easy way around Gmail’s limitation is to change the file extension of the file you are sending. If you have an executable file inside a Zip archive, and you change the archive’s file extension from .zip to .zzz, for example, Gmail doesn’t know what a .zzz file is and does not scan it. Voila, you can now easily send executable files through Gmail.
