	Recently, I found my Mac plus slows down while it duplicates files.  It
takes very long(1 to 2 minutes) to update the desktop files.  And sometimes, it
also takes long for the system to launch a application.  The configuration
is as follows:
	
		Mac Plus with 2.5MB RAM
		LaCie 80MB HD and
		System 6.0.5

	There are probably 2100 files on the HD and it 90% full. I used Norton and
DIsk Express II to optimize the disk, but they don't help much with the slow
desktop updating.  The Norton Utility tells me that the system is using 
B-Tree to keep the infomation about files.  This really confuses me since the
update of a B-tree should be fast and it comes out poor.  I don't know if
there is anything I can do with the slow-down.  Any suggestion is welcomed, 
either hardware or software patch.
