Hi, I did a simple check:
$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda5 658M 408M 217M 66% / /dev/sda4 213M 64M 139M 32% /boot /dev/sda7 14G 13G 593M 96% /home /home 40M bin 502M CytoscapeConfiguration 381M Desktop 896M Documents 42M dwhelper 12K etc 2.4M include 149M lib 1.8M Maildir 32K Notebooks 3.0M perl5 12M share 1.3G src 13M texmf Once added it up, it won't be 13G, how do I know which files mounted on the /home. I googled a while, and also reboot the system. still the same. Thanks for your suggestions,
