The .ZIP file extension format is a file archive and data compression format originally developed and released in 1989 by Phil Katz. With compatible zip format software, a file or a group of files can be packed (compressed) into a single .zip archive which can later be unpacked (decompressed). The zip file archive format facilitates the distribution of multiple files as single archives particularly over the internet and networked systems. Many operating systems have native support for the file format and can usually open zip archives without the need for third party software. Microsoft windows for instance has had native support for the ZIP format since Microsoft Windows 98, similarly Apple's Mac OS includes ZIP support through its default archive file handle Archive Utility.
.bz2 is the filename extension associated with the bzip2 data compression format. It is an open source data compression and decompression tool developed by Julian Seward in 1996. The compression and decompression format is cross platform compatible and comes bundled with versions of Linux and UNIX. The latest of Bzip2 exists as an open source library for download and customization. Earlier versions have executables that can be run directly on Microsoft Windows.
FreeFileConvert uses tuned encoding for ZIP to TBZ2 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload ZIP files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized TBZ2 results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent TBZ2 audio with dependable progress tracking.
Many other common filename extensions use the ZIP format in one aspect or another, for example JAR, .WAR, .DOCX, .XLXS, .PPTX, .ODT, .ODS, .ODP all utilize the ZIP format. The ZIP format provides for data integrity through the CRC32 specification with support for digital signatures. It also supports multiple compression algorithms but commonly utilizes the DEFLATE algorithm.
Bzip2 compresses data using the Burrows-Wheeler block-sorting text compression algorithm, and Huffman coding. It is a client of the libbzip2 library. Because the bzip2 is built on top of this freely available library, users are free to create their own programs to compress and decompress bzip2 files.
