Method and computer-readable carrier for loading data file content Invention relates to loading content from an electronic data file. A method and a computer-readable carrier for loading electronic data file content are disclosed. According to the method, destroyed parts of a data file are identified and attempts are made to restore the said parts. The destroyed parts are not loaded if they cannot be restored.
