Using google to search files by extension

Previous post i showed you how to use google operator to view a public webcam. Now another useful command i'll show you but it is for searching files by extension. What it is extension? Usually, extension is the substring which follows the last occurrence, if any, of the dot character (e.g. txt is the extension of the filename readme.txt, html the extension of mysite.index.html, pdf is the extension of the filename readme.pdf).

Enough explanation, i think i just move forward to the command. The command we'll use here is "filetype" and "ext" without quote(both command will give you the same result). Below is the example:


Replace note with your filename!

filetype
Search Adobe pdf files.
note filetype:pdf

Search Microsoft Powerpoint files.
note filetype:ptt

Search Microsoft Word files.
note filetype:doc

You can use this command to search others format such as mp3, mp4, 3gp, and so on.
To use "ext" command, just replace it with "filetype"(example: note ext:pdf).
