NetDrive, The Network Drive for Windows.
NetDrive connects remote storage like a local hard disk. With NetDrive, managing your remote storage(ftp/ webdav) server will be as easy as any old file folder 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.
NetDrive is free for non-commercial home use. Commercial use requires a license.
