Both WebDrive and NetDrive are excellent commercial products which allows a WebDAV share to be attached as drive letters in Windows. We've had nothing but success with these products. At the time of writing, WebDrive can be purchased from South River Technologies ( https://www.southrivertech.com). NetDrive ships with Netware, is free of charge, and can be found by searching the web for “netdrive.exe”. Though it is freely available online, users are required to have a Netware license. (If any of that sounds odd to you, you're not alone. See this page on Novell's website: https://www.novell.com/coolsolutions/qna/999.html)
