Hi all,

I have an application that uses one configuration file which should be
the same for all users. This conf file should also be editable by any
user.

1) For Win2000 and WinXP it was not a problem to use the
SHGetFolderPath function with CSIDL_COMMON_APPDATA which would then be
smth like: "C:\Documents and Settings\All Users\Application Data" and
to put there the conf file for my application.
The problem is that on Vista the call of
SHGetFolderPath/SHGetKnownFolderPath with CSIDL_COMMON_APPDATA gives
the: "C:\ProgramData" directory which is read-only and _hidden_. If I
put the conf file there the users won't be able to modify the conf
file because it's a hidden directory. Is there any other place
recommended by Microsoft where one could put the application data that
is not _user_ specific and it's not _hidden_?

2) As a possible solution to the above problem I was thinking of using
the CSIDL_COMMON_DOCUMENTS. It doesn't sound right to me, but it's the
only way out that I found until now. What makes me wonder is that if I
print the return value of SHGetFolderPath/SHGetKnownFolderPath with
CSIDL_COMMON_DOCUMENTS I get: "C:\Users\Public\Documents" even though
in windows explorer is no such directory, it's only the "Public
Documents", I mean: "C:\Users\Public\Public Documents". Why is this
confusion between "C:\Users\Public\Documents" and
"C:\Users\Public\Public Documents"?

Thank you in advance,
Viv
