Windows: If you routinely work with WebDAV as a method of file transfer you're likely disappointed in the native Windows support for it. BitKinex is an all-in-one tool for FTP, SFTP, and WebDAV transfers.
If you've had trouble mapping your WebDAV to a network drive—and if you're a Windows 7 user, it's a common problem—BitKinex is a lightweight drag-and-drop solution for transferring files to a remote WebDAV dump as well as other file servers. It supports two-pane browsing, drag-and-drop file transfer, multiple transfer protocols, and brings all the comfort of a traditional FTP client to WebDAV file transfer.
Although it lacks the dead-simple interface of a mapped drive, BitKinex is a close second in ease of use. BitKinex is a free application and works wherever Windows does. Have a favorite tool for working with WebDAV transfers? Let's hear about it in the comments below.
