触摸文件以更新文件的日期/时间？ （修改日期）（WindowsXP的BatchScript）

什么是批处理脚本命令摸上的一个文件，以更新其日期和时间设置为当前日期和时间？ （修改日期）

What's a batch script command to touch on a file to update its date and time to the current date and time? (Modified Date)

例如，乔吹送我这是他几个月前创建一个文本文件，当他的邮件我的文档，我要跟踪它是从我收到了（不是当他创造吧）天怎么老这样我想更新文件的日期/时间设置为当前日期/时间。

For example, Joe Blow sends me a text document which he created months ago, when he emails me the document, I want to keep track of how old it is from the day I received it (not when he created it) so I want to update the file's date/time to the current date/time.

我有一个批处理脚本来自动剔除那些没有在90天内编辑的文件，所以这是麻烦的，当我收到一个特别旧的文件，然后突然消失。

I have a batch script to automatically weed out files that haven't been edited within 90 days, so this is troublesome when I receive a particularly older file then all of a sudden it disappears.

和我需要它通过一个批处理脚本，因为我有数百个文件进行管理，它的归档文件。

And I need it via a batch script as I have hundreds of files to manage, and it's for archiving files.
