Notes:

• SharePoint indexes all content in a site, even if not in the File Types list. You can search for any of the data in the columns of the library to find the file. For example you can search for "jpg" and find everything that has jpg in the filename, description, or other column. You can't search for the file using "filetype:jpg" though.
• If the file extension is added to the File Types list then SharePoint treats the item as a "file" and you can then search using "filetype:jpg".
• If the file extension is in the File Types list AND there is a Format Handler or iFilter then the content of the file will also be indexed.
• You can dump the list of installed Format Handlers using this PowerShell script:
• $ssa = Get-SPEnterpriseSearchServiceApplication
  Get-SPEnterpriseSearchFileFormat -SearchApplication $ssa | ft –AutoSize
• The above list of files has nothing to do with Blocked File Types (files users cannot upload)
