现在有个问题请教大家：

c盘下有两个txt文件，不知道文件名（因为文件名随机产生的），只知道一个大

小是10K，一个大小是20K，D盘下也有两个txt文件，名字分别是1.txe 2.txt

如何用批处理根据C盘里这两个文件的大小来获取文件名，然后复制D盘里的

1.txt到C盘覆盖掉10K大小的这个文件，并把名字改为获取的10K文件的名字，复

制2.txt到C盘覆盖掉20k大小的这个文件，并把名字改为获取的20k文件的名字？

D盘里面的1.txt和2.txt的路径未知吗？

abcd大哥已经帮我解决，谢谢版主的热心啦。。

可以告知如何解決嗎?:P

根据C盘里这两个文件的大小来获取文件名

WMIC DATAFILE WHERE "Drive='c:' and Extension='txt'
and FileSize='10240'" get name


WMIC DATAFILE WHERE "Drive='c:' and Extension='txt'
and FileSize='20480'" get name

這樣:
D:\test>WMIC DATAFILE WHERE "Drive='q:' and Extension='txt' and FileSize='10240'" get name
沒有可用的例項。

D:\test>WMIC DATAFILE WHERE "Drive='d:' and Extension='txt'and FileSize='20480'" get name

你的大小不符合吧？
