 #Here is a quick way to get all IP addresses assigned to your #computer:

 #requires -Version 

 $ipaddress = [System.Net.DNS]::GetHostByName($null)
 Foreach ($ip in $ipaddress.AddressList)
 {
   $ip.IPAddressToString
 }
 If you replace $null with a hostname (like "server123"), you can retrieve the IP address(es) assigned to that computer instead, too.

 #And if you are just interested in IPv4 addresses, try this:

 #requires -Version 

 $ipaddress = [System.Net.DNS]::GetHostByName($null)
 foreach($ip in $ipaddress.AddressList)
 {
   if ($ip.AddressFamily -eq 'InterNetwork')
   {
     $ip.IPAddressToString
   }
 }

if  exist "D:\"  (
    echo aaa

    goto DecompressOnDiskD

) else (
    goto DecpmpressOnDiskC

)

goto ChangeIp
