100%原生的DELPHI编写的ZIP/UNZIP 全功能开发包,包含全部源代码. Delphi 4, 5, 6, 7, 2005, 2006, 2007 and 2009 compatible C++ Builder 4, 5 6, 2007, and 2009 compatible The VCLZip Delphi component allows you to add ZIP and UNZIP capabilites to your application. This component is different from most other "ZIP" development libraries in that it is written in 100% Delphi Object Pascal code and is full featured. There are no DLL's to tote around. This component links right into your application's executable. It is very easy to use. Just SOME of the features include: Create zip files fully compatable with PKZip Completely native Delphi VCL (NO DLLS) Create Disk Spanning and Blocked zip files Delphi 4, 5, 6, 7, 2005, 2006, 2007 and 2009 compatible C++ Builder 4, 5 6, 2007, and 2009 compatible Zip directly from streams to zip files Unzip directly to streams from zip files Stream to Stream zipping and unzipping Unzip directly to memory buffers Zip directoy from memory buffers Create and read Zip and File Comments Create Self Extracting Zip Files (16 bit and 32 bit distributable Windows sfx stubs included (source included for these too) or use your own stubs) Complete support for encrypted files (encrypts as it zips) Save Relative Path information Unzip using Relative Paths (even if zip file wasn't created with relative path info) Use enhanced wildcards Exclude List (tell VCLZip which files not to include (use wildcards too)) NoCompress (STORE) List (tell VCLZip which files to just store (use wildcards too) Set your own temp directory Plenty of events Long filenames, even the 16 bit VCLZip/VCLUnZip Includes comprehensive Zip Utility with source as demo Includes a small stream zipping demo Includes a context sensitive help file Use Unicode filenames, archive names, and pathnames (except for Delphi/BCB 4 and5) . No Royalties! AES Strong Encryption Zip64 capabilities, properties, methods and events: Uncompressed, Compressed, and Archive file sizes can be up to 2^63-1 bytes in length. You can compress up to 2147483647 files into an archive. This is compatible with PKZip's Zip64 format. If a file does not extend beyond any of the original limitations (filesizes of 4 gig or 65535 files) then no Zip64 format information is included in the archive. property isZip64 - tells you when you are working with a zip file that is using Zip64 format. Faster processing due to linking to Zlib 1.2.3 object files for compression and decompression routines. Blocked Zip Files (spanned zip archives split onto hard drive) Compatible with PKZip and WinZip split archives file naming format. For backwards compatability you can tell VCLZip to use the old VCLZip filenaming format by using the BlockMode property

利用哈夫曼算法实现压缩解压缩，Linux c

QT下对资源的压缩解压缩，这个是Quazip源码和zlib源码，用法如下： Quazip+zlib下载地址 点击这里 下面开始讲使用方法： 1：点击上面的连接，下载下来，解压到工程目录底下。（quazip和zlib两个文件夹） 2：在你心间的QT 工程右击添加现有文件，将这两个文件夹的内容添加上去。 3：调用头文件，如下： #include "zlib/zlib.h" #include "quazip/JlCompress.h" 4：使用接口： // 压缩文件夹 JlCompress::compressDir("/usr/local/123.zip", "/usr/local/abc"); // 解压缩文件夹 JlCompress::extractDir("/usr/local/123.zip", "/usr/local/abc");

利用哈夫曼编码进行对已有文件进行重新编码可以大大提高减小文件大小，减少存储空 间。但是，这要求在首先对一个现有文件进行编码行成新的文件，也就是压缩。在文件使用时，再对压缩文件进行解压缩，也就是译码，复原原有文件。试为完成此功能，写一个压缩解压缩软件。 一个完整的系统应具有以下功能： （1）压缩准备。读取指定被压缩文件，对文件进行分析，建立哈夫曼树，并给出分析结果 （包括数据集大小，每个数据的权值，压缩前后文件的大小），在屏幕上输出。 （2）压缩。利用已建好的哈夫曼树，对文件进行编码，并将哈夫曼编码及文件编码后的数 据一起写入文件中，形成压缩文件(*.Haf)。 （3）解压缩。打开已有压缩文件(*.Haf)，读取其中的哈夫曼编码，构建哈夫曼树，读取其 中的数据，进行译码后，写入文件，完成解压缩。 （4）程序使用命令行方式运行 压缩命令 ：SZip A Test.Haf 1.doc 解压缩命令：SZip X Test.Haf 2.doc 或 SZip X Test.Haf 用户输入的命令不正确时，给出提示。 （5）使用面向对象的思想编程，压缩/解压缩、哈夫曼构建功能分别构建类实现。

使用C++多文件编程，纯手写堆和哈夫曼树数据结构实现英文文件内容的压缩和解压 压缩和解压模块互相独立 , 可扩展性强。

上传的主要介绍的是关于JAVA程序设计实现zip的功能，希望大家借鉴一下，对自己的学习有所帮助

ADPCM压缩解压缩 ，已经在用的代码，供大家参考。已经在用的代码，供大家参考。

代码是在c++代码移植到DELPHI平台的，测试过都没问题，但是不排除有BUG。
