This class is necessary due to an annoying bug on Windows NT where instantiating a JFileChooser with the default FileSystemView will cause a "drive A: not ready" error every time. I grabbed the Windows FileSystemView impl from the 1.3 SDK and modified it so as to not use java.io.File.listRoots() to get fileSystem roots. java.io.File.listRoots() does a SecurityManager.checkRead() which causes the OS to try to access drive A: even when there is no disk, causing an annoying "abort, retry, ignore" popup message every time we instantiate a JFileChooser! Instead of calling listRoots() we use a straightforward alternate method of getting file system roots.
