An alias file contains an alias record, stored as a resource of type 'alis', that

points to the target of the alias.The alias file might also contain the target

object's icon descriptions. The Finder identifies an alias file by setting the

isAlias bit in the file's Finder flags field (For a description of Finder flags

An alias file that represents a document typically has the same type and

creator as the file it represents. However, many desktop objects-such as

disks, folders, and the Trash-do not have file types. Instead, alias files for

these objects are assigned special file types, called alias types. Here are the

alias types for those desktop objects for which users can provide aliases:

Desktop object type Alias Constant

Apple Menu Items folder 'faam' kAppleMenuFolderAliasType

AppleShare drop folder 'fadr' kDropFolderAliasType

Application 'adrp' kApplicationAliasType

Control Panels folder 'fact' kControlPanelFolderAliasType

Exported AppleShare folder 'faet' kExportedFolderAliasType

Extensions folder 'faex' kExtensionFolderAliasType

File server 'srvr' kContainerServerAliasType

Floppy disk 'flpy' kContainerFloppyAliasType

Folder 'fdrp' kContainerFolderAliasType

Hard disk 'hdsk' kContainerHardDiskAliasType

Mounted AppleShare folder 'famn' kMountedFolderAliasType

Other objects that can contain files 'drop' kContainerAliasType

P references folder 'fapf' kP referencesFolderAliasType

PrintMonitor Documents folder 'fapn' kPrintMonitorDocsFolderAliasType

Shared AppleShare folder 'fash' kSharedFolderAliasType

Startup Items folder 'fast' kStartupFolderAliasType

System Folder 'fasy' kSystemFolderAliasType

Trash 'trsh' kContainerTrashAliasType

(The Extensions, P references, Apple Menu Items, Control Panels, Startup

Items, and PrintMonitor Documents folders are described in

The System Folder and Its Related Directories)

Since users of System 7.0 can replace files with aliases, if your application

opens a file or a directory without going through the Finder or the

Standard File Package (if, for example, it uses preference files or

dictionary files), it should always call the ResolveAliasFile function just

before opening the file.
