bit7z is a C++ static library which allows to compress and extract many file archive formats, all through a clean, simple and entirely object-oriented interface with the dynamic libraries from the 7-zip SDK. It supports compression and extraction to and from the filesystem or the memory.
bit7z supports the following features:
- Compression of files and directories with the following archive formats: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM.
- Extraction of the following archive formats: 7z, ARJ, BZIP2, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, GZIP, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, TAR, UDF, VHD, WIM, XAR, XZ, Z and ZIP.
- Support to compression and extraction to and from memory (compression to memory is supported only for BZIP2, GZIP, XZ and TAR formats).
- Creation of encrypted archives (only for 7z and ZIP formats).
- Archive header encryption (only for 7z format).
- Choice of the compression level (from none to ultra, depending on the output archive format).
- Solid archives (only for 7z).
Please note that the presence or not of some of these features depends on the particular .dll used along with bit7z. For example, the 7z.dll should support all these features, while 7za.dll should support only the 7z file format and the 7zxa.dll can only extract 7z files. For more information about the 7z SDK DLLs, please see this wiki page.
The release packages contain a precompiled version of the library and they are available for both x86 and x64 architectures.
Obviously, you can also clone/download repository this repository and build the library by yourself (please, see the wiki).
