As you know, there are many types of Exchange 2013 logs, and a lot of disk space is used - and - space on system disk. Theoretically, you can change paths of all logs in Powershell.

Parsing sites and web-pages with Powershell / Invoke-WebRequest / getElementsByTagName and fight with performance

There is a Invoke-WebRequest cmdlet in Powershell, that actually parse HTML-page by tags and content. Cmdlet give you an object of page with ParsedHtml property. To this field you can apply methods to extract needed data.
Assume you need to get all links from the page. See how it works.
