## â¡ï¸ Introduction
**bit7z** is a _cross-platform_ C++ static library that allows the _compression/extraction of archive files_ through a _clean_ and _simple_ wrapper interface to the dynamic libraries from the [7-zip](https://www.7-zip.org/ "7-zip Project Homepage") project.<br/>
It supports compression and extraction to and from the filesystem or the memory, reading archives metadata, updating existing ones, creating multi-volume archives, operation progress callbacks, and many other functionalities.
## ð¯ Supported Features
+ **Compression** using the following archive formats: **7z**, XZ, **BZIP2**, **GZIP**, TAR, **ZIP**, and WIM.
+ **Extraction** of many archive formats: **7z**, AR, ARJ, **BZIP2**, CAB, CHM, CPIO, CramFS, DEB, DMG, EXT, FAT, GPT, **GZIP**, HFS, HXS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, **RAR**, **RAR5**, RPM, SquashFS, TAR, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR, XZ, Z, and **ZIP**.
+ **Reading metadata** of archives and their content.
+ **Testing** archives for errors.
+ **Updating** existing file archives with new files.
+ **Renaming**, **updating**, or **deleting** old items in existing file archives.
+ **Compression and extraction _to and from_ memory** and **C++ standard streams**.
+ Compression using **custom path aliases** for the items in the output archives.
+ **Selective extraction** of only specified files/folders **using wildcards** and **regular expressions**.
+ Creation of **encrypted archives** (strong AES-256 encryption; only for 7z and ZIP formats).
+ **Archive header encryption** (only for 7z format).
+ Possibility to choose the **compression level** (if supported by the archive format), the **compression method** ([supported methods](https://github.com/rikyoz/bit7z/wiki/Advanced-Usage#compression-methods "Wiki page on bit7z's supported compression methods")), the **dictionary size**, and the **word size**.
+ **Automatic input archive format detection**.
+ **Solid archives** (only for 7z).
+ **Multi-volume archives**.
+ **Operat
c++调用7-zip sdk和lzma解压7z文件以及编译后的dll库 （942个子文件）
