The .7z filename extension is associated with the 7z compressed file archive format and the open source 7-zip compression utility both developed by Igor Pavlov. The format had its initial release in 1999. It consists of a start header 32 bytes in size which contains the signature and link to the ending header, followed by the compressed data, a metadata block, and finally the end header. 7z supports limited recovery options for 7z archive files which can open but for one reason or another cannot extract due to CRC or other data related errors.
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 T7Z to TAR conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload T7Z 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 7z compressed archive format was designed to be extensible, to allow it to easily adopt new compression algorithms as they are released. As of writing, the 7z format had support for seven compression algorithms namely LZMA, LZMA2, PPMD, BCJ, BCJ2, BZip2, and DEFLATE. The default algorithm used for compression is LZMA. It is also compatible with the stronger AES-256 encryption algorithm and is capable of compressing file structures of up to 16 Exabyte in size. Filenames can use any characters from the Unicode character set. 7z does not ignore errors found in headers of compressed archives, and as such will not open such archives.
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.
