IT技术系统


public

Sigar sigar = new
Sigar();
FileSystem fslist[] = sigar.getFileSystemList();

//
分区的盘符名称
System.out.println("fs.getDevName() = "

// 分区的盘符名称
System.out.println("fs.getDirName() =

// 文件系统类型读取日志的java代码，比如
FAT32、NTFS
System.out.println("fs.getSysTypeName() = "
+fs.getSysTypeName());
//
文件系统类型名，比如本地硬盘、光驱、网络文件系统等
System.out.println("fs.getTypeName() = "
