PowerShell Script that removes VSS bindings and files from a Visual Studio Project

Below is a powershell script I found from the web that I have been using for a while to remove the bindings from SourceSafe.

First, unbind the project from VSS within Visual Studio, then run this script.

# This script removes VSS bindings and files from a VS Project

# First thing to do before running this script is to specify where the project is located
$Folder = "C:\dev\vs\2008\SalesSync"
#first clear the read-only flag from all files
get-childitem "$folder" -Recurse | % {         
        # Test for ReadOnly flag and remove if present 
     if ($_.attributes -band [system.IO.FileAttributes]::ReadOnly) {  
            $_.attributes = $_.attributes -bxor [system.IO.FileAttributes]::ReadOnly 
   }
}

#next delete all files that are *.suo, *.user, and *.*scc - we don't want them in TFS
Get-ChildItem  $folder *.suo -Recurse -Force | Remove-Item -Force
Get-ChildItem  $folder *.*scc -Recurse -Force | Remove-Item -Force
Get-ChildItem  $folder *.user -Recurse -Force | Remove-Item -Force

#next get all the .sln file - and remove the VSS binding information
$files = Get-ChildItem $folder *.sln -Recurse 
foreach ($file in $files) {
 $fileout = $file.FullName + ".new"
 Set-Content $fileout $null
 $switch=0
 Get-Content $file.FullName | % {
  if ($switch -eq 0) {
   if ($_  -eq " GlobalSection(SourceCodeControl) = preSolution") {
    #we found the section to skip - so set the flag and don't copy the content
    $switch=1}
   else {
    #we haven't found it yet - so copy the content
    Add-Content $fileout $_
   }        
   }
  elseif ($switch -eq 1) {
   if ($_ -eq " EndGlobalSection") {
    #last line to skip - after it we start writing the content again
    $switch=2}
   }
  else 
   { #write remaining lines
    Add-Content $fileout $_}
 }
 #remove the original .sln and rename the new one
 $newname = $file.Name
 Remove-Item $file.FullName
 Rename-Item $fileout -NewName $newname
}
