📁 Setting the Working Directory and File Management

The second paragraph delves into the methods of setting the working directory in Spider, which is crucial for file management and script execution. It outlines three different approaches: using the icon in the interface, utilizing the 'os' library to change the directory programmatically, and using the command line command 'cd'. The paragraph explains how to use the 'os' library's 'chdir' function to change the directory and how to navigate through the file explorer to view and interact with files and folders. It also discusses the display of files in the file explorer and how to create new folders or files for organizing scripts and data.
