Work with PZA, LPAQ, ZPAQ files with PeaZip

PeaZip provide full read / write support to paq format family (create, open and extract paq, lpaq, zpaq files) through the Open Source components from Matt Mahomey's PAQ project (released under GPL license), and offers the same GUI frontend to create, browse, and extract *PAQ family archives under Windows and Linux operating systems.

Why to use PAQ, LPAQ, ZPAQ compression

*PAQ family features extremely high compression ratio, superior to LZMA, LZMA2, and PPMd compression algorithms employed in 7Z, RAR, and ZIPX formats, but this comes at cost of requiring more computing power.
Please note PAQ and LPAQ requires the extractor executable being the same version of the compressor which created the archive, PeaZip supports PAQ8O and LPAQ8 out of the box, with other versions available from Additional formats plugin and many more syntax-compatible versions available on original author's PAQ family project pagePAQ data compression software

How to manage ZPAQ archives with PeaZip
ZPAQ, the most recent compressor of the family, is backward compatible, so PeaZip can work as opener / extractor for zpaq files created with different versions of the executable, and supports AES256 encryption, incremental archiving and journaling - especially useful when creating a backup.
Zpaq is the default *paq family format executable for PeaZip and it will be used as example for explaining compression / decompression operations below.

Compress to ZPAQ format

To add files / folders to a new archive or into an existing .zpaq file

  • Create ZPAQ files from system file explorer

    • Context menu entry PeaZip > Add to archive, shows archive creation screen, to set compression settings, output destination, encryption (password protection), and other archiving options.

  • Create ZPAQ files from PeaZip

    • Use Add button (or Add context menu entry) to show archive creation screen

    • Drag and drop files / folders from the system to a PeaZip instance; if you are browsing an existing ZPAQ archive you will be asked if you want to add files to current archive or create a new one

From archive creation screen it is also possible to apply AES256 encryption to password-protect the archive.

From advanced tab it is possible to change compression format to PAQ and LPAQ.
Please note that, unlike PAQ and ZPAQ, LPAQ is a pure compression formats and input data will be added to a TAR archive before lpaq compression.

Update existing ZPAQ archives

Easiest way to update an existing archive is opening it in PeaZip and dragging files/folders to it, read more about how to update existing archives.

Convert archives to ZPAQ format

Converting existing archives from / to .zpaq format is possible using Convert button, which extracts and then re-pack input archive files, view faq about how to convert existing archive files.
Convertig an existing archive to ZPAQ format will likely reduce its disk occupation significantly due the superior compression ratio of ZPAQ format.

Open ZPAQ files

Open paq, lpaq, zpaq files in PeaZip with double click, or context menu "Open as archive" entry, that will attempt to read any user provided file type regardless file extension associations.
Lpaq files would often contain a TAR archive, as lpaq format would otherwise allow compression of a single file at time.

Extract ZPAQ files

Decompress zpaq files from the system

  • Context menu PeaZip > Extract... shows archive extraction screen, to set output path, password (if needed) and other options

  • From Advanced tab of extraction screen it is possible to set  zpaq to perform format-specific tasks:
    • Restore files to original absolute paths, recommended for backup / restore tasks
    • Extract all revisions of each files, useful to spot modifications in archive file containing a set of incremental backup operations
    • Overwrite existing files
  • Select one or more archives and use context menu  Extract here or Extract here (to new folder) for quick extraction with no further confirmation

Decompress zpaq archives from PeaZip application
  • Extract button shows archive extraction screen providing access to all decompression options

  • Extract all to... button starts simplified unpacking procedure, only asking for output path

Manage encrypted ZPAQ files (AES256)

Unlike paq and lpaq formats, zpaq natively supports encryption, which is based on AES256.
To create or extract an encrypted .zpaq file, enter the password from the padlock icon in status bar (in the file/archive browser) or below output address field (in extraction or archiving screens), alternatively click Tools > Enter password / keyfile in main menu, or F9 accelerator key.
