Hello,

the ExcludedFileAttributes property don't work with xfaReparsePoint (on Vista) why?

You cannot exclude a folder's contents through the use of the ExcludedFileAttributes property. It will only exclude the folder entry in the zip file. The folder's contents will still be processed.
 
If we understand correctly what you're trying to do here, you would like the library to offer properties like RequiredFolderAttributes and ExcludedFolderAttributes so as to include/exclude the folder entry AND its content from the archive if the folder has the specified attributes set.
 
We will add this to our list of possible features to implement.
 
In the mean time, you could implement this yourself in the ZipPreprocessingFile event by calling Windows API functions to determine if the current file is a child of a folder which is a reparse mount point and exclude it if so.
