A computer-implemented method, system, and computer program product for managing history metadata of a file. The method may include accessing a first file with delta information. The method may also include determining a portion of the first file to be moved. The method may also include reviewing the delta information of the first file for changes to the portion in the delta information. The method may also include, in response to reviewing the delta information, generating a portion delta history for the portion.
