你显然收到了很多不同的推荐。 我个人选择一个免费的，第三方实用程序是:代理洗劫 Agent Ransack下载 尽管它的名字有点令人困惑，但它工作得很好，可以以各种方式使用它来查找文件。

祝你好运

如果你想要一个GUI, Bare Grep是不错的选择。Gnu grep适合CLI

Yes there is only one program for Windows PC which have solid GUI and it is essential util for me. I work as a developer and on every computer I've had, first thing install XFind program. It is created in 1997 and till now version is 1.0 and till now works and it is the best. Frequently I need to search some string in a ".cs", ".aspx", ".sct" (Visual FoxPro form code file) or just ".*" and XFind scans all files and show me files and another great thing is that you can look where string is in the file. XFind has also some kind of editor. If it binary file it will show you string finded. Try it and use it forever if you are developer like me.
