what's wrong with this "copy to" line

Tech-Archive recommends: Fix windows errors by optimizing your registry

OK, I can't figure this out. sometimes this line works and sometimes it
won;t, and from the same program. Can someone tell me what's wrong with it?
I'm using VFP7 and VFP9 and I get the error "invalid path or filename" but
the path is correct.

COPY TO "C:\WORK\ADHOC\SURFER\M2\INU141" TYPE DELIMITED WITH "" WITH
CHARACTER "|"

If I shorten it down and put it in "C:\work" then it works fine.

Please help!

Thanks!
Buster
