请问file shortcut 是什么东西啊？谢谢

我在书上看到写下面这段话，不知道file shortcut是什么意思，因为我用的SAS EG，好像没有这个东西，想请教各位了，谢谢！
A file shortcut is a temporary, optional name that is used to identify an external file (a file that is created and maintained in your host operating environment, but which is not managed by SAS) to SAS. You can use shortcuts to open, browse, and submit files, and you can reference file shortcuts in your SAS programs
