To display the contents of a namespace extension in file open/save dialogs, the following must be true :

The attributes of the NSETargetInfo object returned from the GetNSETargetInfo method of the root NSEFolder of the namespace extension must include the following attributes : NSEItemAttributes.FileSysAncestor and NSEItemAttributes.FileSystem.

The attributes returned by the GetAtrributes method of folders in the namespace extension (derived from NSEFolder) must include the following attributes : NSEItemAttributes.FileSysAncestor and NSEItemAttributes.FileSystem.

The attributes returned by the GetAtrributes method of non-folders in the namespace extension (derived from NSEItem) must include the following attributes : NSEItemAttributes.FileSystem but not NSEItemAttributes.FileSysAncestor.

The GetDisplayNameEx method override of the folder/non-folder items must return a file system path when the flags parameter includes DisplayNameFlags.ForParsing. This path can be any file system path or even a temp folder/file.

The FileSystemBrowser sample that comes with EZNamespaceExtensions.Net demonstrates these techniques.
