Carrying on the topic of IFilters from the previous post, Adobe does not currently have a 64-bit PDF IFilter.  My recommendation is to use Foxit Software's PDF IFilter.  With SharePoint, if you are running a 64-bit server farm, the other option is to separate the index component functionality to a 32-bit server and load the 32-bit Adobe PDF IFilter.  (Although, I don't believe this to be a real solution in a true 64-bit SharePoint server farm.)

In examining and utilizing Foxit's PDF Filter, I tried their PDF Reader.  What a refreshing experience.  If you are tired of Adobe Reader taking ages to open and load, Foxit's Reader will please you.  It's all the functionality you need in a reader trimmed down with no bloat.  It also comes in x86 and x64 versions.

Give it a try...

The Microsoft IFilter Team has finally released the Microsoft Filter Pack.  This brings IFilters for the following:

• Metro (.docx, .docm, .pptx, .pptm, .xlsx, .xlsm, .xlsb)
• Zip (.zip)
• OneNote (.one)
• Visio (.vdx, .vsd, .vss, .vst, .vdx, .vsx, .vtx)

The Filter Pack works with the following products and is available in both a 32-bit and 64-bit version:

• Office SharePoint Server 2007
• Search Server 2008
• Windows SharePoint Services v3.0
• SharePoint Portal Servicer 2003
• Exchange Server 2007
