Hi friends.

I want to create a directory that my application uses. Now i am creating the 
directory in the Application Folder where the program is installed.

String InstallationPath = ExtractFilePath(Application->ExeName);
String CustomDirectory = InstallationPath + "\\data";

    if(!DirectoryExists("Installation Path\\data"))
        CreateDir(CustomDirectory);

1.How can i stop the user from Opening and Deleting this "data"folder.
2.Can i make the directory only for my application.

All help greatly appreciated.
Thanks
SA

Starting with XP onwards, that is not a good place to store your app's data 
files anymore.  You should now use SHGetSpecialFolderLocation() or related 
function to retreive the CSIDL_LOCAL_APPDATA, CSIDL_COMMON_APPDATA, or 
CSIDL_APPDATA folder location instead, depending on your needs.  You can 
then create subfolders underneath that as needed.  The main reason for this 
is because many of the common folders used in the past are now locked down 
for security reasons and cannot (or should not) be written to anymore.  Such 
as any folders underneath the "Program Files" folder.

Why are you dynamically building up a path variable but then still using a 
hard-coded (and incorrect) string literal instead?

    if(!DirectoryExists(CustomDirectory))

The machine's admin would have to create a new user account that only your 
app knows the credentials for.  It can then log into that account 
programmably and assign it as the owner of any folder that you create, and 
be the only account with access rights to it.  I do not recommend this 
approach, though.  Why are you trying to prevent the user from accessing 
your app's files?
