Is NSFileManager.SetSkipBackupAttribute() also working for (recursive) paths?

Question

I would like to exclude a whole hierarchy of files and folders from the backup using

NSFileManager.SetSkipBackupAttribute()

The documentation is about "files". Can I also pass a path and all files and folders under that path - also those ones added afterwards - won't be backed up either or do I have to set the attribute on every individual file?

Answer 1

Like stated in the documentation the underlying API used (except for iOS 5.0.1) is NSUrlIsExcludedFromBackupKey and according to this answer it is recursive.
