It has to do with your file system-- and file system structures. Realize that computers do not work off of a base 10 system. That is to say 1, 10, 100, 1000-- unit places, something we learn back in grade school. It has significant importance suddenly when you have to convert to a base 2 system. That is to say 1, 2, 4, 8, 16, etc. Depending if you are talking about bits or bytes, it will effect the number. For example-- you MAY think 2.0 GB is 2 000 000 000 bytes. Its not. Try it out with google: http://www.lmgtfy.com/?q=2000000000+bytes+%3D+%3F+gigabytes That explains your 1.88GB As for 4KB used? The file structure has to use some space to establish itself. Think of it as a very small tag that tells an otherwise empty abyss how to organize itself. And when you 'delete' things, they dont always get completely deleted, so it can grow to 72KB that way.
