@DefaultAnnotation(value=edu.umd.cs.findbugs.annotations.NonNull.class)
public class Nzip
extends Application

A comprehensive command line utility which allows you to work with entries in all supported archive files using Unix like commands (cat, cp, rm, mkdir, rmdir, ls etc.).

Please note that TrueZIP is designed for optimum performance. However, this utility features some optional archive drivers which provide additional safety or otherwise unavailable features. Some of these drivers are not used in their default configuration - see TArchiveDetector for more information. For example, the ZIP drivers used in this utility always check the CRC-32 values provided in the ZIP file. In addition, the SFX driver is used which allows you to browse .exe files if they happen to be SelF eXtracting archives (SFX). If they are not however, TrueZIP may spend some considerable amount of time searching for the Central Directory required to be present in ZIP (and hence SFX) files. As a conclusion, this utility should not serve as a performance benchmark.

This class is not thread safe.

Nzip

public Nzip()

newArchiveDetector

protected TArchiveDetector newArchiveDetector()

May be overridden by subclasses to create the TArchiveDetector which provides file system drivers which should use the specified charset if supported.

Note that the archive detector which is returned by the implementation in this class uses some archive drivers which may be pretty slow due to some extra compatibility tests which they perform on every archive.

newArchiveDetector

protected TArchiveDetector newArchiveDetector(Charset charset)
