Windows 7 File System Bug

[Paul Meek]

I have some applications that have been running on Windows XP for years
without problem. These applications effectively copy files from a remote
location to a folder on a PC. The PC has recently been upgraded to Windows
7 and appears to have exposed a 'bug' in the file system. If i run the
receiving application in 'user' mode it copies the files from a remote
location to a specified folder on the Windows 7 machine and the file is
visible within that application. The file is not however visible within
Windows File Explorer. If i run the receiving application by right clicking
and selecting run in Administrator mode I cant see the file from the
application either. If however I receive the file in Administrator mode
then the I can see the file in both Windows Explorer and the Receiving
application. Initially I thought that this was a permissions issue but the
file permissions are identical and I wouldn't expect an application with
user permissions to see a file when an Administrator can not. The only
difference I have been able to establish is that when copying the file with
'user' permissions it has an attribute 'AI' associated with it. If anyone
has any ideas on what is causing this I would be very grateful

Here's what I posted in response to you in alt.comp.microsoft.windows.
BTW-If you're going to post the exact same message in related newsgroups,
cross-post, not multi-post. Keeps answer and follow-ups combined too.

=================================

Care to share what the file paths are in each situation? Could make a
difference. We even talking about the C: drive? A different physical drive
or partition?

It seems obvious that there are other differences, and very far from obvious
that there is any bug involved. Difficulties with security settings
encountered by users are rarely bugs.
This might be below your knowledge level, but if not, navigate to a file you
can access, right click on it and look at the security properties. The
first thing you might spot is that of course it is extremely easy to set a
file's security so that administrators never know it is there and a user can
do whatever they want with it. Perhaps easy is stretching it, but I say
that for stressing the point. A file gets those settings because the PC is
so configured and they might be a mixture of those of the original file, the
folder they are in, or something set by whoever wrote the software.

It looks as though the security in XP differs from that in Windows 7 enough
to cause a difference and the software might need a bit of tweaking, or the
settings of the folder they are in could be set as you want them and so that
files in it get the desired inherited settings.
Sorry this is not very clear but I am trying to be vaguely descriptive
deliberately because one can not give details of what to do about security
settings without knowing all about the PCs involved.
