PeaExtractor

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.
