Yes, although I believe (but can't prove yet) that it will need to be renamed
before it is deleted. In one previous, but less well documented experiment
that I did for myself, I believe I did a simple delete in Win98 and the player
still locked up forcing a reformat. I believe the file left as a directory
entry but marked as a deleted file will still lock up the device.

Filters we not configured other than what came by default. I was quite precise
in my description because of the need to diagnose my current problem. I
reported what I perceived as unexpected behavior by the program - I wouldn't
have intended for it to work that way if it were my program. Of course, I
didn't create it and it may be working as intended. However, if it is not
intended to work this way, then I believe it to be a defect. I'll try the 3.04
pre-release next dianostic session.

Well, you said one would "use EAUTIL to strip all the EAs, a file manager to
delete "WP ROOT. SF" and dfsee to delete EA DATA. SF"". I'm not sure what
dfsee does when deleting a file but I believe that if it does no more than a
conventional file delete, then it is insufficient. In any case, I don't
believe simple file delete is sufficient for either file. For those not
familiar, IIRC, those are not spaces in the file names but an non-printing
ASCII character whose number I can't recall. You can still delete the WPS file
with a "DEL WP?ROOT.?SF" command if you've remove the attributes but DEL "WP
ROOT. SF" will not work if you've used spaces in the file name. Someone,
please correct me if I'm wrong but I thought I remember reading that a long
while back.

Just trying to set the stage that deleting the EA DATA. SF file is not as
simple as removing offending attributes from the file and deleting it.

From the desktop.

I don't believe I said you did. :-). Just in case someone thought that using a
file manager like FM/2 prevented both file's creation, it's not true. It's
only WP ROOT. SF doesn't get created. Only DOS COPY appears to prevent EA
creation but even this may not be true. My batch file work strips the EAs on
the source files before the copy.

A couple of questions on this. It needs to remove WP DATA. SF too in case WPS
has been used. So maybe I should include the following two lines:

attrib -r -s -h x:\WP?ROOT.?SF
del x:\WP?ROOT.?SF

I did a help for at a command line and didn't see the /r CL argument. Does
that mean recurse? Otherwise, I can't be sure beforehand where all the
transfer files have been placed. If this doesn't recurse, I need to process
all existing directories or else, not all directories may be worked.

By the way, what is the upshot of deleting EA DATA. SF when files with EAs have
been placed on the drive. Is there any other risk other than the loss of all
EAs on that volume? Can I avoid using eautil to strip the EA's and just delete
the EA file, since it is FAT?

Thanks. As I mentioned in my response to Tom, I'll be in Dallas starting
Sunday so I'll probably get to it next week.
