This small PowerShell script helps to create a new file inside the folder if file does not exist, if file exists rename it with the date and times. This logic I always use in my scripts when I want to implement logs system for my script. When the file is renamed (While creating new file) it adds date and time to old file name. This way you can have proper logging mechanism for few of my scripts.
