title: DLL size in memory & size on the hard disk
body: <p>Is there a relationship between DLL size in memory and size on the hard disk?</p>
  
  <p>This is because I am using Task Manager extension (MS), and I can go to an EXE in the list and right click -> Module, then I can see all the DLLs this EXE is using. It has a Length column, but is it in bytes? And the value (Length) of the DLL seems to be different from the (DLL) size on the hard disk. Why?</p>
