finding direct links on google......

To download movies, perform a Google search as below:

“YOUR SEARCH TERM HERE” -inurl:(htm|html|php|pls|txt) intitle:index.of “last modified” (mkv|mp4|avi)

Example:
Titanic -inurl:(htm|html|php|pls|txt) intitle:index.of “last modified” (mkv|mp4|avi)

You can use this search trick to download not just movies, but almost any file.

For instance, to download music,

“YOUR SEARCH TERM HERE” -inurl:(htm|html|php|pls|txt) intitle:index.of “last modified” (mp3|wma|aac|flac)

Just change the file format [(mp3|wma|aac|flac) part] to your required format and you will get a search result of sites containing direct download links to your search query. Enjoy!
