Your application can use the Alias Manager to establish and resolve alias records, which are data structures that describe file system objects (that is, files, directories, and volumes). You create an alias record to take a "fingerprint" of a file system object, usually a file, that you might need to locate again later. You can store the alias record, instead of a file system specification, and then let the Alias Manager find the file again when it's needed. The Alias Manager contains algorithms for locating files that have been moved, renamed, copied, or restored from backup.
The Alias Manager lets you manage alias records. (It does not directly manipulate Finder aliases, which the user creates and manages through the Finder.) You might store an alias record, for example, to identify a customized dictionary from within a word-processing document. When the user runs a spelling checker on the document, your application can ask the Alias Manager to resolve the record to find the correct dictionary.
To use this document, you should be familiar with the File Manager's conventions for identifying files, directories, and volumes.
