I tried with File getFreeSpace() also which returns me 0. Is there any other way to do this?

我尝试使用File getFreeSpace()也返回0。有没有其他方法可以做到这一点?

4 个解决方案

#1

How about the older org.apache.commons.io.FileSystemUtils?

旧的org.apache.commons.io.FileSystemUtils怎么样?

#2

try {

    double freeDiskSpace = org.apache.commons.io.FileSystemUtils.freeSpaceKb("/volume"); 
    double freeDiskSpaceGB = freeDiskSpace / 1024 / 1024;
    System.out.println("Free Disk Space (GB):" + freeDiskSpaceGB);

    } catch (IOException e) {
            e.printStackTrace();
    }

#3

Try

System{" df -k | awk '{sum += $4 }i; END {print sum} '"};

#4

public long getTotalSpace();
public long getFreeSpace();
public long getUsableSpace();

Each of these methods returns the requested size, in bytes, of the partition represented by the java.io.File or 0L if a partition cannot be obtained from the File object. Can you report your code?

如果无法从File对象获取分区,则这些方法中的每一个都返回由java.io.File或0L表示的分区的请求大小(以字节为单位)。你能举报你的代码吗?
