Remove everything before 3rd character

[dawgfather]

I have a data set that has a variety of data of any lengths. I am trying to trim off everything before (and including) the 3rd instance of a "\".

Example:

\\share1\test\folder\subfolder

\\share.sharename.com\item\subfolder\somethingelse

\\www.qlikview.com\unansweredquestion\noidea\needhelp

...should yield:

test\folder\subfolder

item\subfolder\somethingelse

unansweredquestion\noidea\needhelp

This is a repeated question similar to https://community.qlik.com/t5/New-to-QlikView/Remove-everything-before-3rd-instance-of-a-character/m...

But you are probably looking for
= mid( Campo, 1 + index( Campo, '\', 3))
