    Script Name: prompts.ps1

    Description:
    This PowerShell script automates several administrative tasks. It presents a switch-based menu
    with five options for the user. Based on the input, the script can:
      1. List .log files using a regular expression.
      2. List folder contents sorted alphabetically and saved to file.
      3. Display CPU and memory usage.
      4. Display running processes sorted by virtual memory usage.
      5. Exit the script.

    Each action includes error handling and descriptive console output.
