类名称：FileUtils

FileUtils介绍

[英]This class provides basic facilities for manipulating files and file paths.

Methods exist to retrieve the components of a typical file path. For example /www/hosted/mysite/index.html, can be broken into:

/www/hosted/mysite/ -- retrievable through #getPath
index.html -- retrievable through #removePath
/www/hosted/mysite/index -- retrievable through #removeExtension
html -- retrievable through #getExtension
There are also methods to #catPath, #resolveFile and #normalize a path.

There are methods to create a #toFile, copy a #copyFileToDirectory, copy a #copyFile, copy a #copyURLToFile, as well as methods to #deleteDirectory(File) and #cleanDirectory(File) a directory.

Common java.io.File manipulation routines.

Taken from the commons-utils repo. Also code from Alexandria's FileUtils. And from Avalon Excalibur's IO. And from Ant.
[中]此类提供了操作文件和文件路径的基本工具。
####路径相关方法
存在检索典型文件路径的组件的方法。例如/www/hosted/mysite/index.html，可以分为：
*[$1$]--可通过#getPath检索
*[$2$]--可通过#removePath检索
*[$3$]--可通过#removeExtension检索
*[$4$]--可通过#getExtension检索
还有一些方法可以#catPath、#resolveFile和#规范化路径。
####文件相关方法
有创建#toFile、将#copyFileToDirectory、复制#copyFile、复制#copyURLToFile的方法，也有删除目录（File）和清除目录（File）的方法。
