CPIO is one of the numerous file archivers that were released for the UNIX operating system. It was developed as a utility to facilitate tape backups of files and file systems as single archive files with the .cpio filename extension. It made its appearance on the UNIX platform in 1979 in Version 7 of the operating system. Compression is not supported by the CPIO format by default, however archived files can later be compressed using popular compression utilities such as GZIP.
.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 CPIO to TBZ2 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload CPIO 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.
CPIO files are stored to disk as binary files. Meta information is also stored in binary as per the original specification. There have been revisions of the format however that used ASCII character set representation to store Meta information. The format has cross compatibility with the TAR archiving format (allowing you to open TAR archives) and can even recognize different byte-order arrangement of different archiving formats. In the POSIX.1-1988 standard the cpio format has a file limitation of 8 GB.
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.
Upload your archive file in the CPIO format from your device, Dropbox, or Google Drive.
Select TBZ2 as the output format and click Convert. Adjust optional settings if needed.
