Hard Drive – How to Clean Up Unnecessary Files

hard drive

Please suggest me any particular unnecessary file that I can clean to back everything to normal condition(temporarily). (i.e. any log or archieve or anything ). My var/log has only 40MB and Home directory has 3GB of space(so I believe that's not a problem). Other than that what I can clean up to make space. 

[user@host]$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_inamivm-lv_root
                       18G   17G     0 100% /
tmpfs                 1.9G     0  1.9G   0% /dev/shm
/dev/sda1             485M   71M  389M  16% /boot
