Yeeeesssss. Portal builders, developers and end users will all love this feature. Now you can access your contents from Total Commander, Windows Explorer or Visual Studio, or anything that supports the WebDAV protocol. You can even map it as a drive. So you can hav P:\ as the root folder of your Portal File System. Check out the screenshot with the first working prototype.
This is a big boost to productivity for both builders and end users, because now you can work from your favourite tools, no need to open Portal Explorer most of the time. When you save a content, it is automatically versioned, there is permission check, etc. You can also open office documents, Word and Excel directly from Office and save it back, so there is no need to download, change and upload files one by one. Drag and drop move and copy also works.
On the screesnhot, there is a Content View open in Visual Studio, there is a Content Type Definition open in IE as XML, and you can see the PFS folders in Windows Explorer and Total Commander, in the latter the PFS root is mapped to Z:\ so the folder is Z:\System\Schema\ContentTypes\GenericContent.
