In a previous tip we illustrated how you can create code snippets for PowerShell ISE v3 script editor using New-ISESnippet.
All custom snippets are stored as XML files in this location:
Join-Path (Split-Path $profile) 'Snippets'
So if you want to share snippets or copy them from one machine to another, simply open the folder and copy the files to wherever you want:
Invoke-Item (Join-Path (Split-Path $profile) 'Snippets')
Or, even shorter:
ii (Join-Path (Split-Path $profile) 'Snippets')
