Office 2007 that allows you to save

Most of us are used to working with Sharepoint using Office 2007 and we are all quite familiar with it by now, but it is fairly obvious that PDF documents have been used for many years and we all love using them. It is therefore inevitable that we will end up putting them and using them in Sharepoint at some point or another.
The only problem is that Microsoft does not support this file format in any of it's UI interfaces even though it can be uploaded to a document library due to the fact that it is a binary file. The purpose behind this blog therefore is to show you how to improve the user experience using PDF files in the following areas:
    * Indexing and searching PDF documents using Sharepoint Search.
    * Creating  a PDF icon on Sharepoint that is displayed in the user interface.
    * Installing the PDF add-on for Office 2007 that allows you to save PDF files directly from Office 2007.
Installing the PDF I-filter for Sharepoint Search
To understand why you need to do this, it is probably a good idea to explain how Sharepoint Search works in a bit more detail. I am going to assume that you are running the Enterprise edition of MOSS 2007 without restrictions when outlining the next section.
The search engine in Sharepoint can do the following:
    * Index all the meta data inside lists and document libraries within Sharepoint.
    * Index the actual content inside the documents stored in Sharepoint
    * Index external locations outside Sharepoint like file shares, Exchange Public folders and even databases.
    * Index the content inside documents located on these external locations.
It is like having your own private Search engine on your network just like you would search on the Internet. The problems start coming in with the ability of the Search engine to index the content inside documents. This is done via an IIS extension called I-filters and they need to be installed on the Sharepoint server where the Search engine is configured.
