Description: The ‘FileSystemWatcher’ is a class in C# that allows developers to listen for and react to changes in the file system. This class is part of the System.IO namespace and provides an efficient way to monitor specific directories and files. By using the ‘FileSystemWatcher’, programmers can receive real-time notifications about events such as file creation, modification, or deletion. This is particularly useful in applications that require constant synchronization with the file system, such as text editors, backup applications, or content management systems. The class allows for configuring filters to observe only certain types of changes, optimizing performance and reducing system load. Additionally, the ‘FileSystemWatcher’ is easy to implement, making it an accessible tool for both beginners and experienced developers. Its ability to handle asynchronous events also allows applications to continue functioning without interruptions while monitoring changes in the file system.
