Default Disk Uses More Space Than Size of Files

In addition, Windows Explorer will never show you the size of Alternate
Data Streams (ADS) added to a file. For example, I can create a .txt
file whose primary data stream chews up only, say 5KB but then add an
alternate data stream that is gigabytes in size. Windows Explorer,
'dir', and other normal file utilities will only show you the size of
the primary data stream.


You know the implication of this is that a hacker who gains control of your
system could hide an entire encrypted partition inside the ADS of a single
file and most users would never have any clue that this existed.

Given that it would surely be useful to have a service running 24x7 that
looked for abnormally large files or ADS streams on specified partitions and
sent out a warning when any are found.
