Q:

Where are my saved files in home folder?

I reinstalled my UBUNTU 12.04 after facing some crashing issues with my software. I have separate partitions for / and /home.
Output of df -h:
root@sougata-SATELLITE-L750:/home# df -h
Filesystem   Size   Used   Avail   Use%   Mounted on
/dev/sda1    29G    3.8G   23G     15%    /
udev         2.0G   4.0K   2.0G    1%     /dev
tmpfs        402M   860K   401M    1%     /run
none         5.0M   0      5.0M    0%     /run/lock
none         2.0G   22M    2.0G    2%     /run/shm
/dev/sda6    558G   182G   348G    35%    /home

It shows 182 GB used in the /home folder but I can't find those files in /home anywhere.
Output of ls -l /home:
root@sougata-SATELLITE-L750:/home# ls -l /home
total 96
drwx------ 2 sougata sougata 16384 Oct 10 2012 lost+found

Are those files saved inside the lost+found folder ? 
If so then how do I recover them & view them now?

A:

The command du will show you the disk space used by your files and directory.

du -sh /home/* will show you the size of each subdirectory directly below the /home directory, afterwards depending on your preferences you might then:
Either run the same command against one of these directories to manually step one level lower (for instance du -sh /home/sougatapc/*),
Or display a complete recursive listing of your directories and files sizes (du -h /home, remove the -s argument ("summary") and do not forget to remove the /* too at the end of the path: this will allow you to catch any potential hidden directories and files too).

Thanks to this you should be to quickly pinpoint where the largest files or directories are located.

A:

Your home folder contains two directories you own, /home/sougata and /home/sougatapc. The 182 GB you look for are these subdirectories plus possibly in an hidden one.
To display hidden directories, use ls -la /home.
On the other hand, unless you had a file system corruption and some files and directories were recovered with fsck, your lost+found directory should be empty.
