只要做到这一点，它不会需要，只要你想。

Just do it, it won't take as long as you think.

更新由于您使用的是Windows XP，你可以在 sort命令UnxUtils 的。我使用的一个可能比Linux版本越多，它也同样快。

Update Since you're using Windows XP, you can get the sort command in UnxUtils. I use that one probably more than the linux version, and it's equally as fast.

对于大文件真的对磁盘速度的瓶颈问题..我的服务器上面有一个快速SATA RAID。如果你的机器是台式机或笔记本电脑，那么你的7200转（或5400）RPM IDE驱动器将在几分钟添加到作业。

The bottleneck for huge files really disk speed .. my server above has a fast sata raid. If your machine is a desktop (or laptop), then your 7200 RPM (or 5400) RPM IDE drives will add a few minutes to the job.
