To accommodate languages that don't have italics (such as Japanese), in Mac OS 8.5 another distinguishing mark was added, badging with an 'alias arrow'-a black arrow with a small white border-similar to that used for shortcuts in Microsoft Windows. In System 7 through Mac OS 9, aliases distinguished themselves visually to the user by the fact that their file names were in italics. macOS applications can programmatically use the old behavior if required.ДЄliases are similar in operation to shadows in the graphical Workplace Shell of the OS/2 operating system.

In Mac OS X 10.2 and later releases, the new file is found, matching the behaviour of symbolic links. Before Mac OS X 10.2, however, such an ambiguous alias would consistently find the original moved file, rather than the recreated file. With symbolic links the reference is unambiguous (soft links refer to the new file, hard links to the original). The question can arise of how an alias should work if a file is moved, and then a file is created with the same name as the original moved file, since the alias can be used to locate both the original name and the new location of the original file. For example, an application can be moved from one directory to another within the same filesystem, but an existing alias would still launch the same application when double-clicked.

This fault-tolerance sets the alias apart from similar functions in some other operating systems, such as the Unix symbolic link or the Microsoft Windows shortcut, at the expense of increased complexity and unpredictability. Since any of these properties can change without the computer's knowledge, as a result of user activity, various search algorithms are used to find the most plausible target.

Examples of the information used to locate the original are: The operating system stores several pieces of information about the original in the resource fork of the alias file.

The original may be moved to another place within the same filesystem, without breaking the link. While a typical alias under the classic Mac OS was small, between 1 and 5В KB, under macOS it can be fairly large, more than 5В MB (5000В KB) for the alias to a folder.ДЄn alias is a dynamic reference to an object. The purpose of an alias is to assist the user in managing large numbers of files by providing alternative ways to access them without having to copy the files themselves. Likewise, choosing an alias file from within a 'File Open' dialog box would open the original file. When double-clicked, the computer will act the same way as if the original file had been double-clicked.

6 Relation to BSD symbolic and hard linksДЄn alias acts as a stand-in for any object in the file system, such as a document, an application, a folder, a hard disk, a network share or removable medium or a printer.

4.1 Alias record structure outside of size length.

As a descendant of BSD, macOS supports Unix symbolic (and hard) links as well. It is similar to the Unix symbolic link, but with the distinction of working even if the target file moves to another location on the same disk (in this case it acts like a hard link, but the source and target of the link may be on different filesystems, and the target of the link may be a directory). lnk extension, performs a similar function.

In classic Mac OS System 7 and later, and in macOS, an alias is a small file that represents another object in a local, remote, or removable file system and provides a dynamic link to it the target object may be moved or renamed, and the alias will still link to it (unless the original file is recreated such an alias is ambiguous and how it is resolved depends on the version of macOS).
