The cabinet file format, shortened CAB, is an archive file format that was developed for the Microsoft Windows operating system. The format supports the lossless family of data compression algorithms as well as embedded digital certificates that facilitate data integrity. Archives created using the CAB format have the filename extension .cab and are recognized by the operating system through the identifying 4 bytes in the header. CAB enjoys support by other Microsoft technologies such as the Setup APIs, Windows Installer and others. In fact, some earlier integrated development environments developed by Microsoft could create setup files that were organized as CAB files.
The .tar filename was originally designed to be used as a TApe ARchiver to store entire file systems and files as single files on tape storage medium. It was designed by AT&T in 1979. Today, the format more commonly refers to an archive or collation of multiple files into a single file with the .tar filename extension. The format is an open source file archive format commonly associated with the UNIX tar command however other data compression tools are capable of effectively compressing and/or decompressing files saved with the .tar file format. Doing so typically adds the compression filename extension to the archive file for example .tar.bz2.
FreeFileConvert uses tuned encoding for CAB to TAR conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload CAB files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized TAR 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 TAR audio with dependable progress tracking.
The CAB format can use any of the three compression algorithms namely DEFLATE (a common compression algorithm supported by many other archiving and compression formats), Quantum compression, or the alternative LZX. A CAB file can contain at a maximum 65535 files in a maximum 65535 folders. The path structure used in the format does not allow the storage of empty folders.
The tar format is a popular means of digital distribution of multiple files over the internet. It should not be confused with compression/decompression format as tar is merely a tool to collate multiple files together. Combined with other compression tools and formats such as bzip2 or gzip, a tar file can then be compressed or decompressed as needed.
Upload your archive file in the CAB format from your device, Dropbox, or Google Drive.
Select TAR as the output format and click Convert. Adjust optional settings if needed.
Download the converted archive file. Each file stays available for up to 5 downloads.
