FDEFINOJR  A great little easy to install app that seamlessly allows you to get around those silly looking win.dat files without manual steps.

If you need to receive files from business associates that send then in win.dat format because of the way their machines and software is configured, this app makes it easy and painless to view their attached files. The senders of win.dat files probably don't know that their files are being sent that way, and, with the broad array of software and operating systems in todays home and workplace, this app will take care of being sure that they mac user has no excuse to stay on a mac! In short, it seems to me that this app keeps up with how Apple keeps up and leads the way with their software. This app almost reminds me of something that is written to address the pc community that is still using programs that are years behind the mac and fixes it.

Nice job Christopher!!
