Get relative path of files in sub-folders from the current directory

Question

Is there any straight-forward way (by use of cmdlets or .NET classes) to obtain only the relative path of a file in a sub-folder from a given path?

eg current folder is C:\MyScript and there is a sub-folder called Data with a file Test.txt, so I would like to see Data\Test.txt instead of C:\MyScript\Data\Test.txt

Answer 1

The Resolve-Path cmdlet has a -Relative parameter that will return a path relative to the current directory:

Set-Location C:\MyScript $relativePath = Get-Item Data\Test.txt | Resolve-Path -Relative 

Answer 2

In case the directory doesn't exist, or the base directory should be different from the current working directory, there's a .NET method [IO.Path]::GetRelativePath(String from, String to).
