Abbrevia is a compression toolkit for Delphi, C++Builder, Kylix, and Free Pascal. It supports compressing and decompressing PKZIP, Microsoft CAB, tar, gzip, and bzip2 archives, and can create self-extracting executables. On Windows it also provides Delphi wrappers for the LZMA, Bzip2, and WavPack SDKs, and PPMd decompression. Abbrevia also has several visual controls that simplify displaying and manipulating archives, including treeview and listview components.

User friendly wizard-based program for extraction of 180+ archive types, including encrypted files (7Z, ARC, PEA, RAR, ZIP, ZIPX) and spanned multi-volume archives (001, R01, Z01), spin-off of PeaZip project. Drag & drop any file on the application to extract it (if supported) or to attempt unpacking of unknown formats and variants. The minimal GUI is meant to keep working with archive decompression as simple as possible. It is primarily targeted to users with no prior experience in handling archive files, or not needing advanced archive management features such as in-archive browsing and search, creation and conversion of archives, etc.
