Adding a new folder in FolderBrowserDialog

Question

This seems odd to me. I'm using FolderBrowserDialog to select a folder which will be the destination of a bunch of files. Whenever create and select a folder within the dialog, the resulting folder always seems to be read-only when I view the folder in Explorer afterwards.

I've checked the documentation for the FolderBrowserDialog.ShowNewFolderButton property but I see nothing about the access settings for the folder, nor have I been able to see a way of changing the access setting to the folder.

You'd think this would be simple. Anyone have any ideas?

Answer 1

The folders created in the dialog box inherit the parent folder permissions. If you need the parent read only and the child not read only, then you'll need to use a filewatcher to look for new directories and change the read only attributes on it, when it sees a new folder.

I actually found that DirectorySecurity.SetAccessControl method met my needs:

            DirectoryInfo dirInfo = new DirectoryInfo(this.destinationText.Text);
            DirectorySecurity dSecurity = dirInfo.GetAccessControl();
            dSecurity.AddAccessRule(
                         new FileSystemAccessRule("SYSTEM",
                                                  FileSystemRights.FullControl,
                                                  AccessControlType.Allow));
            dirInfo.SetAccessControl(dSecurity);
