- isHeadFile
  
  boolean isHeadFile()
- hasSingleEntity
  
  boolean hasSingleEntity()
  
  Querying method to check if a storage file consists of only one singular live entity. This is necessary to avoid dissolving files that are oversized because of one single oversized entity.
  
  Returns:
  
  true if the file containts exactely one live entity.
