New In This Release

PeaZip was updated to 1.11b (no release notes from author) fixing some issues with some antivirus products incorrectly detecting malware within one of PeaZip's utilities. Installer / Format

PeaZip Portable is packaged in a Installer so it will automatically detect an existing installation when your drive is plugged in. It supports upgrades by installing right over an existing copy, preserving all settings. And it's in Format, so it automatically works with the Suite including the Menu and Backup Utility.

Looks like the download link on the homepage is wrong - it's pointing to PeaZip_Portable_1.11b.exe instead of PeaZip_Portable_1.11b.paf.exe

clean update. I like it cause it has some formats peazip has and 7Zip doesn't.

Hi Everybody,

Now we have two applications that from quick look are redundant. I was wandering is there any benefit to use PeaZip over 7-Zip or 7-Zip over PeaZip. I think would be good to have side-by-side comparison page. This page should help the new users to select their favorite application. I wish that I knew enough for those two applications to help, but I don't and I hope to get some help by community.


1) User interface is very different between 7-Zip and PeaZip, in many aspects.
I started writing PeaZip since I felt I was missing some useful functions on archivers I tested, even if I expecially liked (and like) 7-Zip and WinRar user interfaces very much:
- PeaZip offers the feature to save / import the layout of archive you are composing, for future use, like CD-burning applications offers to save / import disk layout.
- You can save the resulting job command line, to use it in batch scripts, or just for learning purpouse; cl may be harder to learn but offer greater flexibility, so I implemented a way to get it out from the frontend program.
- With multiple inclusion / exclusion filter functions, supported for most of archive types, I think the GUI has a good in-archive search mechanism.

2) Supported filetypes:
- PeaZip implement frontend (read and write) for some new, interesting compressor, generally unsupported by mainstream file archivers, like: PAQ and LPAQ families (highest compression ratio), QUAD (fast but powerful compression, very fast extraction), ARC (powerful compression, strong encryption, recovery records) and its native format PEA (strong authenticated encryption).
- Due to many requests received, also ACE extraction is supported; this happens through an external plugin to keep in PeaZip package only software released under OSI-approved licenses.

3) I implemented also other features I felt useful in a file archiver application:
- UPX compressor frontend for executables.
- Plain byte file split/join (not relying on a format-specific spanning scheme).
- Secure file deletion.
- Byte to byte file comparison.
- File checksum/hash utility that supports a whide set of algorithms (Adler, CRCs, eDonkey, MD4, MD5, Ripemd, SHA*, Whirlpool).
