MacBinary
MacBinary is a file format that combines the data fork and the resource fork of a classic Mac OS file into a single file, along with Hierarchical File System (Apple), HFS's extended metadata. The resulting file is suitable for transmission over File Transfer Protocol, FTP, the World Wide Web, and electronic mail. The documents can also be stored on computers that run operating systems with no HFS support, such as Unix or Microsoft Windows, Windows. MacBinary was widely supported on the Macintosh and was built into most communications programs on that platform. Similar solutions were built into most data compression applications on the Mac, and although these did not require MacBinary to survive transmission across non-Mac systems, MacBinary was often added in these cases to preserve longer filenames and other features. The dual-fork nature of the HFS system was not used on Mac OS X, and MacBinary has largely disappeared. Description In contrast to other computers of the era, Macin ...

AppleSingle And AppleDouble Formats
AppleSingle Format and AppleDouble Format are file formats developed by Apple Computer to store Mac OS resource fork, "dual-forked" files on the Unix filesystem being used in A/UX, the Macintosh platform's first Unix-like operating system. AppleSingle combined both file forks and the related Macintosh Finder, Finder meta-file information into a single file, whereas AppleDouble stored them as two separate files. Support for the formats was later added to Unix software such as Network File System (protocol), NFS and Macintosh Application Environment, MAE, but they saw little use outside this small market. AppleSingle is similar in concept to the more popular MacBinary format, in that the resource and data forks are combined with a header containing the Finder information. In fact, the format is so similar, it seemed there was no reason why Apple did not simply use MacBinary instead, which by that point was widely known and used. Some not-so-obvious reasons are explained in an Internet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resource Fork
A resource fork is a fork of a file on Apple's classic Mac OS operating system that is used to store structured data. It is one of the two forks of a file, along with the data fork, which stores data that the operating system treats as unstructured. Resource fork capability has been carried over to the modern macOS for compatibility. A resource fork stores information in a specific form, containing details such as icon bitmaps, the shapes of windows, definitions of menus and their contents, and application code ( machine code). For example, a word processing file might store its text in the data fork, while storing any embedded images in the same file's resource fork. The resource fork is used mostly by executables, but any file can have a resource fork. In a 1986 technical note, Apple strongly recommended that developers do not put general data into the resource fork of a file. According to Apple, there are parts of the system software that rely on resource forks having only v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PackIt
PackIt is a software data compression utility for archiving and compressing files on the Apple Macintosh platform. It was the first such program to see widespread use on the Mac, and most Mac software archives accepted uploads only in PackIt format for some time. StuffIt, introduced in the summer of 1987, offered much improved compression, and PackIt quickly disappeared. PackIt was written by Harry Chesley to support an online magazine he was writing for at the time, ''MacDeveloper''. To distribute code and sample applications, he needed to archive a number of files into one for transmission. In the original version this was done in a simple manner, simply placing the Finder file information, data fork and resource fork, if present, in a single stream and placing the resulting "block" in the archive. No compression was used, the program was purely an archiver, similar to the Unix tar utility in concept. Like tar, the format did not include an archive header of any sort. To extract ...

BinHex
BinHex, originally short for "binary-to-hexadecimal", is a binary-to-text encoding system which was used on the classic Mac OS for sending binary files over email. BinHexed files take up more space than the original files, but avoid data corruption by software that is not 8-bit clean. History TRS-80 BinHex BinHex was originally written in 1981 by Tim Mann for the TRS-80 computer, as a standalone version of the encoding scheme of the popular terminal emulator ''ST80-III'', for users of other terminals. It was used for sending files via major online services such as CompuServe which, not being 8-bit clean, required files to use ASCII armoring to survive. The system became very popular after Mann uploaded it to CompuServe's TRS-80 files area. The original scheme converted the binary file contents to hexadecimal numbers, encoding those as ASCII digits and letters (0–9, A–F), and adding a newline after every 60 characters. The system quickly gained the addition of a checksum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classic Mac OS
Mac OS (originally System Software; retronym: Classic Mac OS) is the series of operating systems developed for the Mac (computer), Macintosh family of personal computers by Apple Computer, Inc. from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. It was included with every Macintosh that was sold during the era in which it was developed, and many updates to the system software were done in conjunction with the introduction of new Macintosh systems. Apple released the Macintosh 128K, original Macintosh on January 24, 1984. The System 1, first version of the system software, which had no official name, was partially based on the Lisa OS, which Apple previously released for the Apple Lisa, Lisa computer in 1983. As part of an agreement allowing Xerox to buy Share (finance), shares in Apple at a favorable price, it also used concepts from the PARC (company), Xerox ...

UseNet
Usenet (), a portmanteau of User's Network, is a worldwide distributed discussion system available on computers. It was developed from the general-purpose UUCP, Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis (computing), Jim Ellis conceived the idea in 1979, and it was established in 1980.''From Usenet to CoWebs: interacting with social information spaces'', Christopher Lueg, Danyel Fisher, Springer (2003), , Users read and post messages (called ''articles'' or ''posts'', and collectively termed ''news'') to one or more topic categories, known as Usenet newsgroup, newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to the Internet forums that have become widely used. Discussions are Threaded discussion, threaded, as with web forums and BBSes, though posts are stored on the server sequentially.

8-bit Clean
''8-bit clean'' is an attribute of computer systems, communication channels, and other devices and software, that process 8-bit character encodings without treating any byte as an in-band control code. History Until the early 1990s, many programs and data transmission channels were character-oriented and treated some characters, e.g., ETX, as control characters. Others assumed a stream of seven-bit characters, with values between 0 and 127; for example, the ASCII standard used only seven bits per character, avoiding an 8-bit representation in order to save on data transmission costs. On computers and data links using 8-bit bytes, this left the top bit of each byte free for use as a parity, flag bit, or metadata control bit. 7-bit systems and data links are unable to directly handle more complex character codes which are commonplace in non- English-speaking countries with larger alphabets. Binary files of octets cannot be transmitted through 7-bit data channels directly. To ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

File Format
A file format is a Computer standard, standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary format, proprietary or open format, open. Some file formats are designed for very particular types of data: Portable Network Graphics, PNG files, for example, store Raster graphics, bitmapped Graphics file format, images using lossless data compression. Other file formats, however, are designed for storage of several different types of data: the Ogg format can act as a container format (digital), container for different types of multimedia including any combination of sound, audio and video, with or without text (such as subtitles), and metadata. A text file can contain any stream of characters, including possible control characters, and is encoded in one of various Character encoding, character encoding schemes.

Fetch (FTP Client)
Fetch is a full-featured GUI-based FTP client for the classic Mac OS and macOS made by Fetch Softworks. In addition to basic FTP functionality, Fetch includes such features as editing files without having to download them and re-upload them. In version 5.0, support for SFTP was added, and in version 5.2, FTPS was added. History Fetch was created in the summer of 1989 by Jim Matthews, an employee of Dartmouth College. At the time, it was intended primarily for internal college use. Fetch was maintained and updated as a Dartmouth software project and was eventually released as shareware, becoming very popular in the Macintosh community. Due to its status as an official product of an educational institution, Fetch was always free for educational users. The first version of Fetch was a desk accessory. For most of the 1990s it competed with Anarchie as one of the two main Mac FTP clients. After being a contestant on the game show ''Who Wants to Be a Millionaire'' in December 2000, ...

Transmit (FTP Client)
Transmit is a file transfer client program for macOS developed by Panic Inc. Transmit is trialware; after a seven-day trial period, the product can only be used for seven-minute sessions until it is purchased. Transmit was originally built as an FTP client and now supports a number of protocols including SFTP and WebDAV and cloud services including Google Drive and Dropbox. Many of the features of Transmit 4 take advantage of technologies Apple introduced in OS X 10.4, such as uploading using a Dashboard widget or the Dock, support for .Mac and iDisk/WebDAV, FTP/WebDAV/S3 servers as disks in Finder (since v4.0), Spotlight, Droplets, Amazon S3 support and Automator plugins. The app was called "Transit" at introduction in 1998, but had to be changed due to a conflict with an existing product. Transmit was originally developed for Classic Mac OS, but that version has been discontinued and made freeware. Transmit for iOS was released in 2014 but removed and retired from the ...
