Hi Nandini,

The information the Finder uses to organize a window's layout is stored 
in the Finder Info for the folder in question (where things like the 
scroll position, view organization etc. are stored) and the Finder Info 
for the individual items (each of which stores the position for the 
item, for instance).

The Finder will set the layout information for a file if it sees the 
"Inited" flag in the FinderInfo's flags field cleared.  Once a position 
in the window has been assigned and the Finder has done its housekeeping 
like reading application icons out of an application's resource fork the 
Finder sets the "Inited" bit to prevent doing the same work again in the 

The layout of this Finder Info field is contained in the various "Inside 
Macintosh" volumes, as well as header files like "Files.h".  It's 
probably on-line in some technote on Apple's web site, too.

Hope that helps,
