need to know how to (as would be known on windows) a disk clean up and disk defrag

There is no online ext3 defragmentation tool that works on the filesystem level. An offline ext2 defragmenter, e2defrag, exists but requires that the ext3 filesystem be converted back to ext2 first. But depending on the feature bits turned on in the filesystem, e2defrag may destroy data; it does not know how to treat many of the newer ext3 features.

Ubuntu's file system is so amazing that it doesn't even need a disk
defragment, there is also this article on cleanup [1]

There is not any on line ext3 defragmentation device that works at the filesystem stage. An offline ext2 defragmenter, e2defrag, exists however requires that the ext3 filesystem be converted back to ext2 first. But depending at the characteristic bits became on within the filesystem, e2defrag may also ruin information; it does now not understand the way to treat many of the more recent ext3 features.
