强制删除文件夹中的所有文件 [英] Force Delete all files from a folder

问题描述

我一直在使用特定的一段代码来删除文件夹中的文件，但是这样做很成问题，因为我可能忘了关闭一个或两个InputStream。我所拥有的代码太大了，我无法看到所有没有关闭的输入流。是否有删除文件的方式是否有打开的InputStream？

这是我一直在使用的代码块;

  File fin = new File（C：/ ABC Statements final /）; 
 File [] finlist = fin.listFiles（）; 
 for（int n = 0; n  if（finlist [n] .isFile（））{
 System.gc（）; 
 Thread.sleep（2000）; 
 finlist [n] .delete（）; 
} 
} 
  

我编辑了代码。这个版本的工作原理。

解决方案

在提供的代码块中没有InputStream实例。

要不写大量未经测试的IO代码，请查看 apache.commons.io 项目。特别是在 FileDeleteStrategy 类中，用于文件删除操作。

您的代码可能如下所示：

  File fin = new File（ C：/ ABC声明final /）; （文件file：fin.listFiles（））{
 FileDeleteStrategy.FORCE.delete（file）; 
 
 
} 
  

I have been using a specific piece of code to delete files from a folder but it is proving very problematic because maybe I forgot to close an InputStream or two. The code I have is so big that I am not be able to see all the Inputstreams that I have not closed. Is there a way of deleting files whether there is an open InputStream or not?

This is the piece of the code that I have been using;

File fin = new File("C:/ABC Statements final/");
    File[] finlist = fin.listFiles();       
    for (int n = 0; n < finlist.length; n++) {
        if (finlist[n].isFile()) {
        System.gc();
        Thread.sleep(2000);
            finlist[n].delete();
        }
    }        

I have edited the code. This version works.

解决方案

There is no InputStream instances in the provided chunk of code.

To not write lots of untested IO code, please take a look at the apache.commons.io project. Especially at the FileDeleteStrategy class, for file deletion operations.

Your code might look like that:

File fin = new File("C:/ABC Statements final/");

for (File file : fin.listFiles()) {
    FileDeleteStrategy.FORCE.delete(file);
}
