Downloading Wsp from SharePoint Central Admin

Recently I got a requirement to check the contents of a wsp which was already deployed on the Client's SharePoint server.  I have given access to Central Admin, but as you know SharePoint will not provide us any link to download/extract the deployed wsp. 

These are the ways I found on the web to download/extract the wsp..

• Using Power Shell Script
•  Using Code

1. Using PowerShell script :

$myFarm = Get-SPFarm

$myWSP = $myFarm.Solutions.Item("documentspacenew.wsp").SolutionFile

$ myWSP.SaveAs("c:\purna\ documentspacenew.wsp")

 

This will be saved as 

 

2.  Using Code :

  protected void btnGetWSP_Click(object sender, EventArgs e)
        {
            SPSolutionCollection allSolutions = SPFarm.Local.Solutions;
            foreach (SPSolution mySolution in allSolutions)
            {
                SPPersistedFile myWSP = mySolution.SolutionFile;
                if (myWSP.Name == "documentspacenew.wsp")
                {
                    myWSP.SaveAs("c:\\Purna\\" + mySolution.Name);
                }
            }
        }

Here the SPSolutionCollection , SPPersistedFile classes are referred from   Microsoft.SharePoint.Administration namespace.

Finally I have got the contents of the downloaded solution by changing the extension from .wsp to .cab.

 

Hope Helpful..!
