Uh oh, sorry, no. The Vista behaviour is not a surprise, it's rather
due to a mistake on my side. The permissions of the target folder
(where the files and directories are moved to) didn't allow to create
files, only directories. This explains why I could move directories but
no files into that folder with restricted accounts. Sorry again.

Actually Vista behaves like every other system, except XP, moving a file
or directory opened for delete-on-close succeeds for all accounts.

I looked into the permissions on my XP system again, but the permissions
of the target folder allow to create files and directories for every
user. So it appears I developed and tested this on the only system
showing this behaviour.

Hi Corinna,

Really thank you for the effort of collecting so much information! Yes, I
understand you want to find out the root cause of this behavior(I am
curious either). However, this behavior may hide deep in the
kernel-mode(most probably in File System level), so finding the root cause
really goes out side of my scope.

Anyway, I will forward your useful information to the File System and wait
for their further comment. I hope they will provide some insight for this
behavior. Thanks.

Best regards,
Jeffrey Tan

Hi Corinna,

Sorry for letting you wait.

Actually, I still did not get any further feedback from the File System dev
team yet, I assume they are busy now. In this situation, if you still want
to find out the root cause, I recommend you repost your problem in
microsoft.public.development.device.drivers newsgroup. There may be some
File System expert to help you find out the root cause.

Anyway, once I got any further feedback from the File System dev team, I
will paste here.

Thanks for your understanding.

Best regards,
Jeffrey Tan

Thanks for your help. Actually it's not *that* important anymore, now
that I have a solution working nicely on all NT versions, and given the
fact, that this behaviour apparently only occurs on XP. So, if you get
some interesting reply it would be nice if you could share it, if you
don't get it, well, never mind.


Thanks again,
Corinna

Hi Corinna,

Thanks for your feedback!

Thanks for your patient and understanding. Yes, MSDN newsgroup support
nature normally makes it hard to find out the root cause of such type of
complex issue. Also, since we have no official channel of contacting the
Windows dev team, I can only send consulting emai internal to contact them
indirectly. So if there is no response from the dev team, it is rude for me
strike them.

Anyway, I will try to contact that File System developer privately again, I
hope he will have time to response.

Thanks again for your understanding.
