The Ultimate script to download Ignite sessions that I posted earlier this week was pretty popular, and some fellow community members asked for the same script for the Microsoft Build Conference earlier this year. That is why I created this PowerShell Script so everyone can easily download them whether they were present at Build or not! Here are the features:

• Downloads all the Microsoft Build Conference Sessions and Slides
• Groups them by folders
• Makes sure no errors come up due to Illegal File names.
• If you stop the script and restart in the middle, it will start where it left off and not from beginning

This is what it will look like at the end:

*I will update total size of downloads in the following week!

Here is the script if you want to see the code, however my WordPress plugin breaks some PowerShell, so DO NOT copy it from my blog, instead download it from Technet galleries here

Make sure you send it out to all your twitter friends by clicking the image below!

Download the script from here!  Do not copy paste from below!

Here is the source code:
