问题

超级用户读者Sebastien想知道如何在Windows 8中同时搜索多种文件类型：

I am looking for files in a particular directory that have the following extensi***: .txt, .csv, and .xml. The directory has many levels of sub-directories that I would like to search through for all three file types in one go.

When I use Ctrl+F in Windows Explorer and enter extension types like *.txt;*.csv;*.xml, I watch the search bar fill up with green for a long time, but end up with no results. I know there are hundreds of these file types in the parent directory and sub-directories though.

How can I do a search like this in Windows 8 that returns results?

Sebastien有没有一种简单的方法可以同时搜索多种文件类型？

答案

超级用户贡献者AppsDev为我们提供了答案：

Open Windows Explorer and in the top right search box type *.extension. For example, to search for text files you should type *.txt.

For multiple file types use Ext:.doc OR Ext:.txt OR Ext:.pdf. Hope this helps you.

特别注意：如讨论线程中的附加注释所述，在搜索多个文件类型时，请确保单词“OR”大写。
