Bulk compaction of 700GB of PST files?

OK, I accomplished this using SmartPST (Freeware) and AutoIT (Freeware.)

With SmartPST I can bulk add PST files into my Outlook profile. Drag and drop.

And the following AutoIT script I dug up iterates through each and compacts. Run it in a VM to not get your current work avoided.

This ended up being the best I could ask for. A drag and drop, then click solution. :) IT Automation doesn't get better than that.

#include <GUIListView.au3>
SplashTextOn("Compacting now", "This may take hours...", 250, 40)
;//Runs the mail application that is in control panel.
$Path = FileGetShortName(RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Cpls", "mlcfg32.cpl"))
Run(@SystemDir & "\control.exe " & $Path)
Opt("WinTitleMatchMode", 4)
WinWait("Mail Setup - Outlook", "Setup e-mail accounts and dire")
ControlClick("Mail Setup - Outlook", "Setup e-mail accounts and dire", "Button2")
WinWait("Account Settings", "AcctMgr Tab")
;//Gets list of data files listed
$sTitle = "Account Settings"
$hWnd = WinGetHandle($sTitle)
If @error Then
 MsgBox(0, "Error", "Unable to find window")
EndIf
WinActivate($hWnd)
$hlist = ControlGetHandle($hWnd, "", "[CLASS:SysListView32; INSTANCE:2]")
If @error Then Exit
$arraycount = _GUICtrlListView_GetItemCount($hlist)
Local $ltext[$arraycount]
$i = 0
Do
 $ltext[$i] = _GUICtrlListView_GetItemText($hlist, $i)
 $i = $i + 1
Until $i = $arraycount
;//Goes into each listed Data file and compresses them

 Sleep(1000)
