Following from How To Search For Directory Listings 1 on how to accurately locate directory listings, now it is time to apply some of the advanced operators to filter out the unwanted results. Here are 4 ways to narrow your result of directory listings.
Narrow Results by Site
Use the site operator to narrow results to a particular site's directory listing.
Use the site operator to narrow results to a particular site's directory listing.
Example: intitle:index.of "parent.directory" site:wikipedia.org
Narrow Results by Sub-Directory
Use the inurl operator with the name of the sub-directory to narrow results to that sub-directory. The following example returns only directory listings that contains sub-directories with the name "admin".

Example: intitle:index.of "parent.directory" inurl:admin
Note that when combined with directory listing search, Google blocks the results from displaying the more popular audio and video file formats such as mp3, mp4, wma, wmv, ogg, avi, etc. The only popular video file format I have found that still works in such searches is the Flash Video format (flv). To overcome this, submit the filetype as an ordinary search term. This, however, does not guarantee that the results will contain your desired file type.
No result example: intitle:index.of "parent.directory" ext:mp3
Narrow Results by Specific File
This is easy if you have throughly understood the basic and advanced operators. Just include the file name and extension you wish to locate. Use double quotes to restrict your search further. Use the OR and period operators to expand your search.
Example: intitle:index.of "parent.directory" "this.is.an.example.mp3"
