Configuring PDF related stuff for SharePoint 2010 (and 2007) is very simple, yet annoying and often forgotten SharePoint configuration step. There are nice articles (link, link) to help you configure it but when you do it manually chances are you will misconfigure something.

I wrote a simple PowerShell script to automate this, and it will do everything for you > configure PDF Icon and PDF crawling.

Here is what you need to do:

• Download and install the Adobe PDF iFilter
• Configure SharePoint Foundation search service via Central Admin (or PowerShell)
• Download the Adobe PDF icon (select Small 24 x 24, but resize it to 17 x 17) and save it to a folder on your SharePoint server as pdficon_small.gif
• Download the script below and place it to the same folder as Adobe PDF Icon
• Run the script as administrator from Powershell shell

Special thanks to Agnes Molnar for testing this script. If you want to learn more about PowerShell and SharePoint 2010 check SharePoint 2010 Unleashed.

Update May 4th 2011. – Agnes Molnar – added Adobe to PATH variable
