alias (noun), pl aliasesAn alias to a file or a folder on disk.
An alias object is very much like a file object. You can form an alias specifier in just the same way as you form a file specifier, and an alias object can often be used in the same places where a file object would be used. But there are some important differences:
- The item on disk that an alias represents must exist when the specifier is encountered at runtime. Thus an alias cannot be used to create a file or folder.
- An alias value can be assigned directly to a variable.
- An alias can continue pointing to an item on disk even if the item is moved or renamed.
