Extract and Download All Installed Solution Packages (WSP Files) in SharePoint

There were many solution packages installed in my current SharePoint environment. During a server replacement we noticed that the WSP file for a particular solution is missing in TFS! (Our version control repository!)

Thankfully, we have a solution to this issue using: http://archive.msdn.microsoft.com/SPSolutionExtractor. To extract and download all installed solution WSP files, Just execute:  
SharePointFarmSolutionExtractor.exe -extractAll c:\SharePointSolutions

which will extract all WSP files from installed solutions! 

Download deployed solutions(WSP) from central admin with PowerShell in SharePoint 2010: 

?

1 2 3 4 5 6 7 8 9

$dirName = "c:\Solutions" foreach ($solution in Get-SPSolution) {     $id = $Solution.SolutionID     $title = $Solution.Name     $filename = $Solution.SolutionFile.Name     $solution.SolutionFile.SaveAs("$dirName\$filename") }

If you want to download a particular solution, use this PowerShell Script:

?

1 2 3

$farm = Get-SpFarm $SolutionFile = $farm.Solutions.Item("SolutionName.wsp").SolutionFile $SolutionFile.SaveAs("D:\SolutionFile.wsp")
