1. A computer-implemented process for encoding files to be stored in a distributed network, comprising the process actions of:

  • calculating optimal file size ranges corresponding to different erasure resilient coding (ERC) number of fragments, wherein each number of fragments is the optimal number of fragments for a corresponding range of file sizes;

    inputting a file of a given file size;

    if the file size is smaller than the range of the file sizes for the smallest ERC number of fragments of two, encoding the file without using erasure resilient coding;

    if the file size of the input file corresponds to a range of file sizes, encoding the file using erasure resilient coding and the optimal number of fragments corresponding to the file size range of the input file.
