一份csv直接转换过来的dat文件，有2.8G大小，但是打不开，提示如下：


op. sys. refuses to provide memory
    Stata's data-storage memory manager has already allocated 1520m bytes and it just attempted to allocate another 16m bytes.  The   operating system said no.  Perhaps you are running another memory-consuming task and the command will work later when the task   completes.  Perhaps you are on a multiuser system that is especially busy and the command will work later when activity quiets down.
    Perhaps a system administrator has put a limit on what you can allocate; see help memory.  Or perhaps that's all the memory your    computer can allocate to Stata.





什么意思啊？如何才能打开？谢谢！
