    - #### expand

          public void expand(File archive,
                             File targetDirectory)
                      throws IOException,
                             ArchiveException

      Expands `archive` into `targetDirectory`.

      Tries to auto-detect the archive's format.

      Parameters:
        `archive` - the file to expand
        `targetDirectory` - the directory to write to
      Throws:
        `IOException` - if an I/O error occurs
        `ArchiveException` - if the archive cannot be read for other reasons

    - #### expand

          public void expand(String format,
                             File archive,

      Expands `archive` into `targetDirectory`.
      Parameters:
        `archive` - the file to expand
        `targetDirectory` - the directory to write to
        `format` - the archive format. This uses the same format as accepted by `ArchiveStreamFactory`.
      Throws:
        `IOException` - if an I/O error occurs
        `ArchiveException` - if the archive cannot be read for other reasons

          @Deprecated
          public void expand(InputStream archive,
                                         File targetDirectory)
                                  throws IOException,
                                         ArchiveException

      Deprecated. this method leaks resources
      Expands `archive` into `targetDirectory`.

      Tries to auto-detect the archive's format.

      This method creates a wrapper around the archive stream which is never closed and thus leaks resources, please use `expand(InputStream,File,CloseableConsumer)` instead.

      Parameters:
        `archive` - the file to expand
        `targetDirectory` - the directory to write to
      Throws:
        `IOException` - if an I/O error occurs
        `ArchiveException` - if the archive cannot be read for other reasons

    - #### expand

          public void expand(InputStream archive,
                             File targetDirectory,
                             CloseableConsumer closeableConsumer)
                      throws IOException,
                             ArchiveException

      Expands `archive` into `targetDirectory`.

      Tries to auto-detect the archive's format.

      This method creates a wrapper around the archive stream and the caller of this method is responsible for closing it - probably at the same time as closing the stream itself. The caller is informed about the wrapper object via the `closeableConsumer` callback as soon as it is no longer needed by this class.

      Parameters:
        `archive` - the file to expand
        `targetDirectory` - the directory to write to
        `closeableConsumer` - is informed about the stream wrapped around the passed in stream
      Throws:
        `IOException` - if an I/O error occurs
        `ArchiveException` - if the archive cannot be read for other reasons
