FSRefs have the property you desire. As of Snow Leopard, though, the new recommended technique is to use a file reference NSURL. Check the NSURL documentation and also: http://developer.apple.com/mac/library/documentation/cocoa/conceptual/LowLevelFileMgmt/Articles/FileManagementNSURL.html Note that an alias _record_ is different from an alias _file_. An alias record is data in memory and is suitable for this purpose, but perhaps overkill. As of Snow Leopard, alias records are deprecated in favor of bookmark data, but, again, it's probably overkill. (Both alias records and bookmark data are more suitable if the reference is to be persisted for use by a later process. Also, both can apply more robust searching heuristics to find an appropriate file even if it isn't the original. For example, if the original is deleted and replaced with a new file of the same name.)
