Enabling PDFs and Other File Types
SharePoint does not include built-in support for file types invented by other companies such as Adobe PDF files. That means that by default, Search does not look inside PDF files, and when you upload a PDF file it doesn't appear with the correct icon.
To enable search within PDF files:
Download the PDF text filter (ifilter60.exe) from http://www.adobe.com/support/downloads/detail.jsp?ftpID=2611.
Run ifilter60.exe to install the filter on the server.
To add the PDF icon to SharePoint:
Download the PDF icon file from http://www.adobe.com/images/pdficon.gif.
Save the file to this folder on the server:
C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\IMAGES
Edit the DOCICON.XML file found in this folder on the server:
C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\XML
Add the following line to the
<ByExtension>element:<Mapping Key="pdf" Value="pdficon.gif" OpenControl=""/>
Save and close DOCICON.XML.
Run iisreset.exe to load the changes.
You can use the same technique to enable Search and add icons for other file types. In each case, the filter and icon comes from the originator of the file type, however, since it owns the file format.
