Yes, we do, internally we use absolute paths (for the FileSelection,
FileStatus, ReadEntryWithPath).
By the way it is possible to convert paths to absolute ones just before
retrieving, but converting immediately after deserializing has advantages:
avoiding of the keeping the metadata with appropriate `baseDir`, avoiding of
the over number of checking the type of the path and avoiding an extra
converting paths (when the data is retrieved several times from one metadata
object).
