This article introduces the method of node.js using fs.rename to force rename or move a folder. First, it introduces the usage of rename, 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!"); 
 } 
});
Copy after login

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

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 may 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);
 }
Copy after login

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