PeaZip can also be used to try to open any arbitrary file extension with “Open as archive” menu entry, as many file formats are simply variants of archive formats (especially of zip standard).
Even more file structures (forensic file types, WavPack compressed files, etc) can be parsed extending PeaZip capabilities via standard 7-Zip Codecs, copying extra codecs to PeaZip’s folder in res\7z\Codecs path.
In example a large family of codecs (compatible with PeaZip and 7-Zip) is available here7Z codecs – please note TC4Shell codecs are free but closed source, so they can be freely downloaded and installed by end users but they cannot be distributed within PeaZip packages.

PeaZip is localized over than 30 languages and is capable of handling all most popular archive formats (200+ file types), supporting a wide array of advanced file and archive management features (search, bookmarks, thumbnail viewer, find duplicate files and compute hash/checksum value, add, update and edit files inside existing archives, convert archive files…), especially focused on security (strong file encryption, two factor authentication, encrypted password manager, secure file deletion…).
The distinctive trait of PeaZip is the innovative and easy to use compression/extraction interface, more similar to CD burners interfaces rather than to a classic file compressor. This design makes extremely simple to check (and update) items set for compression and extraction, integrating a full featured file manager component.
Also, tasks created in the GUI can be easily saved as batch scripts, in order to automate backup operations, or for fine tuning, or for learning purpose, bridging the gap between the ease of use of GUI applications and power and flexibility of console.

CODE
Legacy code cleanup
QOL improvements
Added info popup if Browser optimization (Options > Settings, Performances group) is set to fast or no pre-parse, to inform some archive TOC and data issues may go unnoticed, even preventing archive content to be correctly displayed in some cases.
Minor performances optimization in pre-parsing step for very large archives, up to -15% time for reference 250K items archive
Modal forms are now positioned centered to main form, consistently with most apps
Modal forms confirm and cancel action made as consistent as possible with standard OK/Cancel buttons and Esc/Enter keys
Various fixes
Fixed browsing archives when 7z alias is set
Fixed hiding comment label in status bar when archive comment is deleted
Fixed Windows context menu direct archive creation entries, now enumerate directory content consistently with other functions
Security fixes
(.pea format) Fixed path traversal evasion on extraction, vulnerability and poc reported by Harshit Gupta
(Windows) Fixed sanitization of input for functions invoking PowerShell, vulnerability and poc reported by Harshit Gupta
