What help do you need? Just clear out some extra files in /

[yashraj]

You will have to remove unwanted files that are located in / file system. It could be either compressed files of third party sofwares or backup files. You need to run 'ls' command and will have to find out folders consuming big diskspace. You can use
"du -sh" too.

If you are confused, just paste here output of "ls" command..
