本文整理了Java中java.io.File.getTotalSpace()方法的一些代码示例，展示了File.getTotalSpace()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。File.getTotalSpace()方法的具体详情如下：
包路径：java.io.File
类名称：File
方法名：getTotalSpace

File.getTotalSpace介绍

[英]Returns the total size in bytes of the partition containing this path. Returns 0 if this path does not exist.
[中]返回包含此路径的分区的总大小（字节）。如果此路径不存在，则返回0。
