WEBDAV netdrive

With NetDrive, managing your remote FTP and WebDAV servers will be as easy as any old file folders on your PC. Once you mount the local drive, you don't need to run an application or an FTP client interface but a simple drag-and-drop in your Windows Explorer will be sufficient to transfer and manage files.
