Windows 7 64 bit with JDK 1.6.38 / 1.7.11


For some TAR.GZ archives generated by Maven Assembly Plugin, TruzZip canno find all files.

  • Do not work on TAR.GZ
  • Do not work on TAR if GZ was decompressed with TrueZip.
  • Work on TAR if GZ was decompressed with 7-zip.

I cannot upload the example TAR.GZ at the moment because of restrictions in my company, but I could do it soon.

public static void main(String[] args) throws Exception {

	final TArchiveDetector detectorGz = new TArchiveDetector("gz", new TarGZipDriver(IOPoolLocator.SINGLETON));
	final TArchiveDetector detectorTar = new TArchiveDetector("tar", new TarDriver(IOPoolLocator.SINGLETON));
	final TFile gz = new TFile(args[0], detectorGz);
	final TFile tar = new TFile(gz.getParentFile(), "extracted.tar", detectorTar);

	TFile.cp_r(gz, tar, detectorGz, detectorTar);

public static void recursive(final TFile file) {

	if (!file.isDirectory()) {


	final TFile[] children = file.listFiles();

	System.out.println(file + " (" + children.length + ')');

	for (final TFile child : children) {

The driver setup is wrong: The TarGZipDriver reads and writes TAR.GZ files , not just GZ files. The latter is not an archive file format, just a compressor format.
