Since MSN Messenger 7.0.0732 (a private BETA build), Microsoft has changed the file transfer with MSN Messenger in an effort to to set a halt to the increasing number of MSN Messenger viruses annoying everyone of us since the beginning of 2005. From now on "unsafe" file extensions* will be blocked immediately from getting through.

We're pretty sure that with the blocked file extensions strategy, Microsoft is chasing ("potential") MSN Messenger users away. So I guess it's our job to avoid that and tell you how to pass by this file extensions embargo:

1) What you could do is rename the file before sending it. For instance, call it readme.txt, send it over and then tell the person on the other end to rename it back to whatever it used to be.

2) Method number one is somewhat tedious if you transfer files regularly. That's why wtbw made us a quick and easy patch that enables the blocked file types again by marking them "safe" after all. Download File Extension Unblocker, launch it and restart MSN Messenger completely. Now if you share File Extension Unblocker with your contacts, you'll hardly notice any obstruction when transferring files over MSN Messenger.

3) If you're using MSN Messenger 7.0.0777 (the final release), you can also use Mess Patch to enable the transfer of "potentially unsafe files" again. Download Mess Patch and in the Conversation Window Options, make sure you check the Remove File Transfer Blocked Extensions tweak. Of course, you can select all the additional Mess Patch tweaks of your choice.

4) Another method to transfer blocked files is to use the File Sharing application from the Activities pulldown menu in your conversation window [thanks to: BenB].

IMPORTANT MESSAGE: Always be cautious about ANY MSN Messenger file transfer you accept. If you are unsure, discuss the content of a transfer with the contact before proceeding.
