The ExcludedFileAttributes property lets you limit the processing of files to only those files that do not have specific file attributes on. This property affects the list of files specified in the FilesToProcess property.
Files that have the file attributes specified with the ExcludedFileAttributes property will be tagged as "excluded" when the ZipPreprocessingFile or UnzipPreprocessingFile event is triggered, and will not be processed unless you change the value of the excluded parameter to False.
To specify multiple file attributes that you do not want to process, set the ExcludedFileAttributes property equal to the sum of the values for each file attribute.

The RequiredFileAttributes property lets you limit the processing of files to only those files that have specific file attributes on, as opposed to only processing files that don't have these attributes on.
If you want to create your own, special filters in order to limit which files are processed, you can use the ZipPreprocessingFile or UnzipPreprocessingFile events to specifically exclude files (just set the excluded parameter whenever you want to exclude a file).
The xfaReparsePoint value will only exclude items whose reparse point tag value is of the name surrogate type, as defined by the Windows API macro IsReparseTagNameSurrogate()
