If I recall correctly, zlib (and so, gzip) operate over a data window of 64Kb or less, so your method would not work if the files are bigger than that.

    True-any compression method that uses a data window in a similar manner would experience the same issue, albeit the size at which it would occur would be dependent upon the size of said window. The code above was merely an example.
