Youtube uses two video ids for a single video. One is 11 character and the other is 16 character. We save both of them. But if you observed carefully the file with sixteen character name is just a hard link to the file with 11 character name. So, they are not consuming double the space.

Thank You!

by marlowbg on 29 Dec 2010

How we know that it is a hard link? It looks like a normal file?

by harindra on 30 Dec 2010

there is no soft link,i think it's consumed space twice.

PayPal is safe for online transactions. It's the most popular way.

Thank You!

Hello guyz,

@marlowbg To find the hard linked files, use the following command

find /path/to/youtube/cache/dir/ -xdev -samefile video_id

@Harindra The files are not soft linked. The files are hard linked. All hard links to a file doesn't consume any space on disk.

Thank You!
