.Synopsis Extract the content of an App File to a Folder .Description .Parameter AppFilename Path of the application file .Parameter AppFolder Path of the folder in which the application File will be unpacked. If this folder exists, the content will be deleted. Default is $appFile.source. .Parameter GenerateAppJson Add this switch to generate an sample app.json file in the AppFolder, containing the manifest properties. .Parameter OpenFolder Add this parameter to open the destination folder in explorer .Example Extract-AppFileToFolder -appFilename c:\temp\baseapp.app #> function Extract-AppFileToFolder { Param ( [string] $appFilename, [string]
