What file types can Google index?

Google can index the content of most types of pages and files. The most common file types we index include:

• Adobe Flash (.swf)
• Adobe Portable Document Format (.pdf)
• Adobe PostScript (.ps)
• Autodesk Design Web Format (.dwf)
• Basic source code (.bas)
• C/C++ source code (.c, .cc, .cpp, .cxx, .h, .hpp)
• Google Earth (.kml, .kmz)
• GPS eXchange Format (.gpx)
• Hancom Hanword (.hwp)
• HTML (.htm, .html)
• Java source code (.java)
• Microsoft Excel (.xls, .xlsx)
• Microsoft PowerPoint (.ppt, .pptx)
• Microsoft Word (.doc, .docx)
• OpenOffice presentations (.odp)
• OpenOffice spreadsheet (.ods)
• OpenOffice text (.odt)
• Perl source code (.pl)
• Python source code (.py)
• Rich Text Format (.rtf, .wri)
• Scalable Vector Graphics (.svg)
• Text (.ans, .asc, .cas, .txt, .text)
• Wireless Markup Language (.wml, .wap)
• XML (.xml)

When you use the filetype: operator in a Google search (for example, filetype:xml galway, Google searches for files with the .xml extension, not for files of file type XML.
Not all URLs or pages have the .html file extension. Some pages (like http://www.google.com) have no extension at all, and some have an extension that doesn't match their file type. Limiting your search to a specific file type will return pages with that file extension, and may return fewer relevant results.
