本文整理了Java中org.apache.commons.io.FileUtils.sizeOf()方法的一些代码示例，展示了FileUtils.sizeOf()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。FileUtils.sizeOf()方法的具体详情如下：
包路径：org.apache.commons.io.FileUtils
类名称：FileUtils
方法名：sizeOf

FileUtils.sizeOf介绍

[英]Returns the size of the specified file or directory. If the provided File is a regular file, then the file's length is returned. If the argument is a directory, then the size of the directory is calculated recursively. If a directory or subdirectory is security restricted, its size will not be included.
[中]返回指定文件或目录的大小。如果提供的文件是常规文件，则返回文件的长度。如果参数是目录，则递归计算目录的大小。如果目录或子目录受到安全限制，则不包括其大小。
