Features

The program features an archive browser interface with search and history features for intuitive navigation in archive's content, and allows the application of fine-grained multiple exclusion and inclusion filter rules to the archive; a flat browsing mode is possible as alternative archive browsing method. PeaZip allows users to run extracting and archiving operations automatically using command-line generated exporting the job defined in the GUI front-end. It can also create, edit and restore an archive's layout for speeding up archiving or backup operation's definition. Other notable features of the program include archive conversion, file splitting and joining, secure file deletion, byte-to-byte file comparison, archive encryption, checksum/hash files, find duplicate files,

. In addition, the program's user interface (including icons and color scheme) can be customized. Versions older than 2.6.1 were vulnerable to an improper input validation weakness, that has been patched in following versions. From version 6.9.2 and newer, PeaZip support editing files inside archives (E.g.: Open a text file, add text and save it without unzipping the file); from that version forward, it also supports adding files to subfolders in an already created archive, in addition to maintaining the ability to add files to archives to the root directory.
