How to use fs.rename to implement forced renaming in node.js

This article mainly introduces the method of node.js using fs.rename to force rename or move folders. It has certain reference value. Interested friends can refer to it.

This article introduces Node.js uses fs.rename to forcefully rename or move a folder. First, the usage of rename is introduced, as follows:

[Rename Folder]

// rename.js
var fs = require("fs"); 
 
// 重命名a文件夹为b 
fs.rename("c:a","C:b",function(err){ 
 if(err){ 
  console.log("重命名失败！"); 
 }else{ 
  console.log("重命名成功！"); 
 } 
});

[Note: The folder does not exist, then there will be an error message in err. ]

When we daily operate some files or folders on the computer, the Windows system may pop up a corresponding dialog box, prompting us that the file or folder cannot be renamed. This is because the files or files in the folder are occupied by some running processes on the system. We can find the process occupying the file, end it, and then rename the file or folder. However, this process is relatively cumbersome and difficult to implement through programming.

And when performing a large number of renaming operations in node.js, permission problems will occasionally occur. The solution is simple, use synchronous naming and add a try/catch.

 try {
  fs.renameSync(oldPath, newPath);
 }
 catch (e) {
  fs.renameSync(oldPath, newPath);
 }

It has been tested and effective under win10/node.6.15

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
