Indexing Service Links

In order to index a file's contents, the Windows Indexing Service must open the file, find all the words it contains, and record those words in an index. Indexing Service accomplishes this with the help of IFilter DLLs, dynamic link libraries that know how to extract text and properties from various file formats. Windows 2000 comes with IFilters for Microsoft Office, HTML, and text files. To filter additional file types, such as Adobe Acrobat documents, you will need to install an appropriate IFilter. This table lists the IFilters we know about:

For information on the file types indexed by Windows XP Indexing Service, see Microsoft KnowledgeBase article Q309447. (This article actually documents a problem, so be sure to read through its Resolution section!)

ActiveState Tool Corp. makes ActivePerl, a very good Perl package for Windows. The "official" and ActiveState documentation should agree with each other; we've listed both sources due to differences in presentation and in case one isn't working.
