WinTar can create and read several different archive formats, including most popular tar variants, Pax , several cpio formats, both BSD and GNU ar variants. ZIP, 7Z and Windows CAB archives. It also can write shar archives and read ISO9660 CDROM images. For single compression files, WinTar supports creating and extracting Gzip, BZip2,Unix compress (LZW), LZMA and Huffman coding algorithms. |
Archive File
Archive files were originally used to store important files on alternate media (such as tapes) for preservation and recoverability. Archive files are now commonly used for transferring files and for software distribution and installation. A hard drive volume, RAID, and shadow copy/snapshot can also be considered archive files. The operating system would be the file archiver. An archive file is a file that is composed of one or more files along with metadata that can include source volume and medium information, file directory structure, error detection and recovery information, file comments, and usually employs some form of lossless compression. Archive files may also be encrypted in part or as a whole. Archive files are used to collect multiple data files together into a single file for easier portability and storage. Computer archive files are created by File archiver software, Optical disc authoring software, or Disk image software that uses an archive format determined by that software. The file extension or file header of the archive file are indicators of the file format used. Archive files are sometimes accompanied by separate parity files that allow for additional error detection and recovery, particularly in recovery of missing package files in a multi-file archive. |
Archive format
An archive format is the file format of an archive file. The archive format is determined by the file archiver. Some archive formats are well-defined by their authors and have become conventions supported by multiple vendors and/or open-source communities. Archive formats support features such as file concatenation, compression, encryption, file spanning, parity/Cyclic redundancy check, checksum, self-extraction, self-installation, volume and directory structure information, package notes/description, and other meta-data. |
Archive Formats supported by WinTar
WinTar can read and extract GNU tar, ustar, pax interchange format, cpio, Mtree, Zip, 7Z, CAB and ISO9660 formats. |
WinTar can create ustar, pax interchange format, cpio, shar formats, Mtree, CAB, Zip and 7Z archive formats. |
|
WinTar can read and write POSIX formats: POSIX-standard formats, including ustar, pax interchange format, and the POSIX cpio formats. |
WinTar supports pax interchange format: Pax interchange format is really an extended tar format. WinTar eliminates almost all limitations of historic tar formats and provides a standard method for incorporating vendor-specific extensions. |
WinTar supports of Gzip, Bzip2, Unix compression highly sophisticated compression algorithms and None compression method. |
|
For single compression files, WinTar supports creating and extracting Gzip, BZip2,Unix compress (LZW), LZMA and Huffman coding algorithms. |
