So the same directory is accessed as \\Users\\mayanksolanki\\Desktop\\Folder\\ In Windows: ‘ \\ ‘ used instead of ‘ / ‘ to escape ‘ \ ‘ character.

In Linux and Mac /Users/mayanksolanki/Desttop/Folder/ Syntax: To specify a directory is different in different operating systems (suppose java file is in a folder named ‘Folder’ is created on desktop)
Syntax: To create a new file File object_name = new File(Directory) Syntax: To import file library or Classes import Secondary, additional work is simply we will be importing File Class for which we will be importing File Class. Here, we will use one of them known as-try-catch block techniques.Ģ. So in order to deal with it, we will be using Exception Handling Techniques. Primary, in order to create a new file, inbuilt files and functions are used which definitely will throw Exceptions here playing it safe. The file is one way, in which data will be stored as per requirement. When the file is getting created indirectly the abstract path is getting created. It is only when “using” that File that the underlying physical storage is hit. ISRO CS Syllabus for Scientist/Engineer ExamĪ File is an abstract path, it has no physical existence.

Here’s an example showing you how to rename a file synchronously: const Fs = require('fs') This method blocks the Node.js event loop for other operations (because it waits for the hard disk) while renaming a file. Node.js also comes with an Fs#renameSync method. In case the newPath points to an existing directory, this method throws an error. Please notice: this method overwrites any existing file at newPath. Here’s an example on how to rename a file in Node.js using the built-in fs module: const Path = require('path')Ĭonst oldPath = Path.join(_dirname, "oldFile.txt")Ĭonst newPath = Path.join(_dirname, "newFile.txt") The underlying operation of renaming a file is the “move” from the previous name to the new one. Well, renaming a file is basically moving a file from one place to another. The Fs#rename method expects two arguments:Īt first, you may expect a file path and the new file name instead of two file paths as the arguments. These promise-based file system methods are usable with async/await. That’s the reason the example uses the require('fs').promises exports available in Node.js v10.0.0 and later. This tutorial assumes you’re using async/await for flow control of your code. Later, Node.js added support for promises and async/await. The callback support comes from the early days of Node.js where asynchronous operations were handled using callbacks. This rename supports callbacks by default. Non-blocking in this case means Node.js processes other operations while waiting for the hard disk to respond. Node.js’ fs core module provides the Fs#rename method as an asynchronous/non-blocking way to rename files on disk.
