+### Example 
+
+```js
+// Let's assume you want to create a text file named hello.txt in the /home/user/documents directory with the content "Hello, world!" 
+
+codebolt.fs.createFile('hello.txt', 'Hello, world!', '/home/user/documents');
+
+```
+
+### Explaination
+
+The codebolt.fs.createFile method is used to create a new file in a specified directory, with content provided as a string. It has three parameters:
+
+fileName (string): This parameter specifies the name of the file to be created. The name should include the file extension (e.g., "example.txt", "data.json").
+
+source (string): This parameter contains the content that will be written into the newly created file. It can be any string data that you want to save in the file.
+
+filePath (string): This parameter defines the path where the file will be created. It should be a valid path in the filesystem where you have write permissions.
