Would this hurt the system software?

Hiya,
	I keep my doc (text/teach/etc) files of my various inits/DAs alongside
with my inits/DAs.  I also have subdirectories inside both the System.Setup and
DA folder.  Would this cause any kinds of problems?  I have tried removing much
of my inits/das (hence the subdirectories) but my system still crashes (6.0)
every now and then, sometimes on the first thing I do (move the mouse)
sometimes not crashing at all.  Shift booting will not crash tho.  Should I
remove all the doc files or do I really have to go thru and weed out the
offending da/inits?
	Also, yesterday, my trashcan decided to disappear for a bit. Switching
off and on the whole system didn't help.  I then changed the floptical id
number from 2 to 0 and the hard drive id number from 5 to 6, and the trashcan
came back.  I did not do anything to the system before the trashcan
disappeared.
	There were also a couple of times when the computer decided to boot
from the floptical instead of the hard drive (after the 3 finger salute) and
and didn't even poll the hard drive.  CTRL-OA-RESET again didn't change
anything.  Booted into Prodos 8 from my 3.5" and could catalog my HD.  But
CTRL-OA-RESET still wouldn't boot from the hd (hd scsi #4, floptical #2). 
Switching off the whole system and restarting solved the problem.
	Is my system just naturally weird or am I doing something to it?  Using
a high speed SCSI and 5 megs of ram.
	Thanx for any and all help!  Ciao.
