ZPAQ File

Compressed file archives created with ZPAQ tool are saved with .ZPAQ extension. ZPAQ is a type of archive format used for creating backups with journaling and incremental backups support. This standard is backward compatible. ZPAQ uses compression algorithms based on deduplication methods such as LZ77, BWT, or context mixing. ZPAQ archive support multilayer compression. ZPAQ tool is a user-friendly command line program available on Windows, Linux, and Mac OS systems.

Format of files with .ZPAQ extension

Files created with ZPAQ offer high compression ratios as well as backward compatibility as each archive contains information about the compression algorithm used. ZPAQ is a self-describing format, and offers support for 256 bit AES encryption. The base compression method used by ZPAQ is considered faster than ZIP algorithm and offers comparable or even higher compression ratios.

ZPAQ files - management

ZPAQ is an open-source format developed by Matt Mahoney. It is used by ZPAQ command line tool. The format is also supported by some archiving tools such as Bandizip, although not always fully. Source code for ZPAQ program is freely available online.
