How to convert absolute path to relative path in PowerShell?

Question

I'd like to convert a path to a relative path in a PowerShell script. How do I do this using PowerShell?

For example:

Path to convert: c:\documents\mynicefiles\afile.txt Reference path:  c:\documents Result:          mynicefiles\afile.txt 

And

Path to convert: c:\documents\myproject1\afile.txt Reference path:  c:\documents\myproject2 Result:          ..\myproject1\afile.txt

I found something built in, Resolve-Path:

Resolve-Path -Relative 

This returns the path relative to the current location. A simple usage:

$root = "C:\Users\Dave\" $current = "C:\Users\Dave\Documents\" $tmp = Get-Location Set-Location $root Resolve-Path -relative $current Set-Location $tmp
