SharePoint 2010 - PowerShell Script to do the sizing - Includes all versions

Introduction

SharePoint 2010 Content Inventory and Sizing tool 

Background

Complete content inventory for selected site collections or for any sub-sites. The content inventory is exported as comma separated text file which can be easily possible to transform to any other file providing information about all sites and individual level size including versioning. A complete and up-to-date Content Inventory provides the following benefits:

• Reusable and scalable PowerShell script
• Helps to improve the overall content quality by identifying stale and abandoned sites and lists and their size
• Documents the site structure and allows to verify that the structure
• Input for better planning of easy to complex content migration project
• Reduce the cost of third purchasing third party tool
• Extensively re-used for doing content inventory and sizing for migration and moving content from one environment to another 

The Content Inventory is PowerShell script so no installation is required.

Using the code

Use PowerShell to run the code - 

I have seen many questions and answers and scattered code and answer to get the sizing of site collection or at any level which can also includes versions and will output a text file which will be comma seperated.

You can convert this C:\outputsize.txt to excel or any file format for further analysis.

Find below the complete code and  used several times in my environment SharePoint 2010 farm environment.
