i have a home partition of 160 gb. i have had this through many upgrades in my time with pclinuxos. my problem seems to be lost space on my hard drive. other than a few big files in home vids and virtualbox i think i should have at least 75 gb free but the properties window says i have 13 gb left. this is really weird as i always keep most of my iso's and other large files on storage drives. what is the best way to check the partition for lost-hidden files etc.
