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

Answer 1

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
