#MAC FILE COMPRESSION TYPE ZIP FILE#

The reason for the format's near universality can be attributed to Phil Katz, the developer of the original ZIP compression algorithm, who placed in the public domain the ZIP file format, its compression format, and the. ZIP works across a wide variety of computing platforms, including Unix and Linux, VMS, OS/2, MS-DOS, Windows, and Macintosh. Like JAR and EAR, WAR use the same compression method as ZIP. WAR, which stands for Web ARchive, brings together all the files that a Java-based Web application needs-Java archives, HTML pages, XML files, and so on-so the application can be run easily on a Web server. At this point, most tar files are compressed using another program, often gzip, resulting in a file with the extension of ".tar.gz" or "tgz." Almost never seen on Windows or Mac OS X, and extremely common on Linux computers. In other words, if you have 100 files, each 3 kb, and you tar them together, you end up with one 300 kb file. TAR files aren't really compressed instead, they're conjoined to form one large file. Does a pretty good job of compressing files. This form of compression is proprietary to Alladin Systems, but their "Expander" program is free for download for both Mac and Windows. Also leaves Mac-specific data intact, like a.

SEA stands for Self-Expanding Archive, and it goes with SIT, discussed next.

#MAC FILE COMPRESSION TYPE SOFTWARE#

Since it is almost entirely used as a tool for Linux software installation, it is extremely rare to find it used to compress normal data files, or to find it on Windows or Mac OS X machines.

#MAC FILE COMPRESSION TYPE INSTALL#

RPM stands for "Red Hat Package Manager." Invented by Red Hat, it is used to build and install individual software packages.

#MAC FILE COMPRESSION TYPE RAR#

His licensing allows for the free decoding of RAR archives, but encoding is only allowed by his company. RAR is a proprietary format developed by Eugene Roshal. One of the few archivers used on computers running the Amiga operating system. It proved to be influential, since the source code was made available by Dr. LHA is a Japanese compression format dating from the 1980s. JAR, like EAR and WAR, uses the same compression method as ZIP. JAR stands for Java ARchive, and is used with archives containing software written in and for the Java programming language. When using FTP, it doesn't matter if you set your transfer to "binary" or "ASCII7" either way, if you're using. bin however, it's safer for traveling around the Internet via email because that fact that it uses ASCII text allows the transfer of binary programs over non-binary transfer protocols like UUCP and sendmail. Converts text and binary files into ASCII text specifically, the 7 bits that most Unix systems use. EAR, like JAR and WAR, uses the same compression method as ZIP. RPM is a similar tool for different distributions of Linux.ĮAR, for Enterprise ARchive, is used with Java 2 Enterprise Edition (J2EE) applications that require multiple JAR and WAR files, discussed afterwards. It's not seen very much any more, since it's been pretty much supplanted by TAR and GZIP.ĭEB is used by the Debian distribution of Linux to package software installation files. Files using this method end in ".bz2."ĬAB is a Microsoft cabinet file, used to distribute software programs.ĬPIO is a Unix command used for copying files into, and out of, archives. It is used on Linux and other Unix-like systems. bin files over FTP only after setting your FTP program to "binary".īZIP and BZIP2 uses the "Burrows-Wheeler block sorting text compression algorithm" (no, I don't know what that means either). Since it's a binary format, you need to transfer. Since both forks are kept together, for example, a decompressed file will still display its actual icon, instead of a generic file icon. Leaves Mac-specific data intact & therefore keeping the "resource fork" together with the "data fork".

Does very little compression, and creates binary files instead of text files. Used on MS-DOS, although other platforms have tools that will uncompress 001 and ARJ files.ħZ is a new format created for use with 7-Zip, an open source Windows-based archiver.ĪRJ files are discussed previously, with 001.īIN is Mac OS-only, & stands for MacBinary. You may also see such files with the extension of. Let's review many of those formats-that way, you can make an informed decision when you're creating your archives.Ġ01 is an extension that indicates that the archive is using the ARJ format for compression.

There are various compression formats, but many of them can be obscure.
