Easy to read text without .txt extension

I was looking for a way to read files that are text but use a different extension than txt, such as .java, .pde, and .bash files. This program does the trick: 1. copy your attachment from email to it, 2. change the extension to .txt
I have used Dropbox to do the same thing, but I dont always want my attachments to go to the cloud. This program lets me keep my files local.
