Dbf:Load(cPath): public: return false/???
  It is the complement of Dbf:Save() method. It enables to restore all data
  files of the program, stored by Dbf:Save(). If it is not possible to
  restore all files the false is returned. If the restoring succeeded
  it is not possible to continue in program immediately (due to indexes,
  filters and reports) but the program is stopped and the user is asked
  for the restart. After restarting the program the files are reindexed
  and the recovery is succesfully finished.
