What is taking up so much space on my disk, beside the filesystem?
I'm a bit curious as to why my hard drive space, according to Disk Usage Analyzer, has 20 GB more used space than the space my files take up. Here's a screenshot:
On "/", it says that only 121.1 GB is used, but apparently 141.1 GB is used. I have 3 partitions on my HDD: a GRUB partition, my Ubuntu partition, and a 3 GB Swap Partition.
So, any thoughts? I really would like to know if I can make this 141.1 GB shrink to the 120 GB that it should be.
