Is there a file explorer control for ASP.NET that works very similar to Windows Explorer? I've seen several that allow for creating directories and uploading files. I'm currently using DevExpress' File Manager Control. It's great but it does not have the functionality to move files around via drag/drop.
Also, I'm looking for something that allows one to open a file, say Excel Spreadsheet, and save it and it saves automatically to the web location it was opened from.
Does anything like this exist out there?
