Scenario

You deploy SharePoint 2013, a few months later you realize that the c:\ drive is running out space. After some investigation, you find that most of the space is take by a specific folder "C:\Program Files\Microsoft Office Servers\15.0\Data". This is the location of the SharePoint Search Index. The recommended practice is to keep the Index on separate disk.

Solution

To move the Search Index, we are going to use PowerShell. To move the index we will need to use about 13 separate PowerShell Commandlets. Luckily, we have simplified it for you.
