Here is the text from Technote #40 that should answer your question:

"The Finder keeps and uses a series of file information flags for each
file. These flags are located in the fdFlags field (a word at offset
$28 into an HParamBlockRec) of the ioFlFndrInfo record of a parameter
block. They may change with newer versions of the Finder. Finders 5.4
and newer assign the following meanings to the flags:

	Bit	Meaning
	0	Set if file/folder is on the desktop (Finder 5.0 and later)
	1	bFOwnAppl (used internally)
	2	reserved (currently unused)
	3	reserved (currently unused)
	4	bFNever (never SwitchLaunch) (not implemented)
	5	bFAlways (always SwitchLaunch) 
	6	Set if file is a shareable application
	7	reserved (used by System)
	8	Inited (seen by Finder)
	9	Changed (used internally by Finder)
	10	Busy (copied from File System busy bit)
	11	NoCopy (not used in 5.0 and later, formerly called BOZO)
	12	System (set if file is a system file)
	13	HasBundle
	14	Invisible
	15	Locked"

Note: The technote warns that these may change under future systems. This is
indeed the case under 7.0. Here are the new meanings:

	Bit	Meaning
	0	isOnDesk - reserved (set to zero)
	1-3	color - three bits of color coding
	4	colorReserved - reserved (set to zero)
	5	requiresSwitchLaunch - reserved (set to zero)
	6	isShared - Application is available to multiple users
	7	hasNoInits - File contains no 'INIT' resources
	8	hasBeenInited - Finder has read BNDL info
	9	Reserved (set to zero)
	10	hasCustomIcon - File or directory has custom icon
	11	isStationery - File is a stationery document
	12	nameLocked - Can't be renamed from Finder
	13	hasBundle - Contains BNDL resource
	14	isInvisible - Invisible from Finder and StdFile
	15	isAlias - File is an alias

This will be documented in the new Inside Mac VI.
