I suspect an implied question is "Why is it so big?"
FWIW as a point of comparison, in XPsp2 I just did a Win-F search of all
under %windir%\winsxs ; then a Ctrl-a, Alt-Enter and found I have
only 246 Files, 44 Folders for a total size of 44.0 MB (46,165,028
and total space of 44.5 MB (46,686,208 bytes) (I haven't done a defrag
in a while I guess. <w>)
And if I limit the search just to *.dll the number of files is only 39
and the total size is cut in half. ; )
