1. A method for extending the storage capacity of a file server in a decentralized storage network, comprising:

  • storing data for an object on a shadow file server;

    generating a range of consecutive data values commensurate with a first size of the object;

    compressing the range of consecutive data values to generate a holey file;

    storing the holey file as size metadata for the object on a directory file server; and

    adding an entry to a directory server table to associate the data and the size metadata for reconstruction of the object.
