Find all Access databases, and Compact and Repair

I'm trying to find all Access databases in a directory and Compact and Repair each without opening Access each time. I found the following article explaining how to find them and write to a file: Batch file to find all Access Databases, but ideally I'd like to just find them and compact without writing to a file.

I have searched how to call the /compact command line functionality, but I don't know how to do it on the databases I find. Can a .bat file be written to do this? Something like:

@echo off

"C:\Program Files\Microsoft Office\Office14\MSACCESS.EXE" "C:\Databases\ /s" *.accdb /compact

Any help with the syntax is very much appreciated.

Consider using Access' dedicated CompactRepair method which you can run in VBA (inside an Access database or outside like in an Excel macro). The thing to note is Compact & Repair actually creates a copy of existing database and replaces it with original, so some file handling is needed.

VBA (inside MSAccess.exe)

Sub RunCompactDBs()
    Dim path As String
    Dim accfile As Variant

    path = "C:\Databases\"
    accfile = Dir(path & "*.accdb", vbDirectory)

    Do While Len(accfile) > 0
        bkfile = Replace(accfile, ".accdb", "_bk.accdb")

        ' CREATE COMPACTED BACKUP
        Application.CompactRepair path & accfile, path & bkfile, False      
        ' COPY TO ORIGINAL PATH
        FileCopy path & bkfile, path & accfile     
        ' DESTROY COMPACTED BACKUP
        Kill path & bkfile                    

        accfile = Dir
    Loop

    Set accApp = Nothing
End Sub

VBA (outside MSAccess.exe)

Sub RunCompactDBs()
    Dim path As String
    Dim accfile As Variant
    Dim accApp As Object

    Set accApp = CreateObject("Access.Application")

    path = "C:\Databases\"
    accfile = Dir(path & "*.accdb", vbDirectory)

    Do While Len(accfile) > 0
        bkfile = Replace(accfile, ".accdb", "_bk.accdb")

        accApp.CompactRepair path & accfile, path & bkfile, False      

        FileCopy path & bkfile, path & accfile                           
        Kill path & bkfile

        accfile = Dir
    Loop

    Set accApp = Nothing        
End Sub

And there's no reason to stick with VBA. Any language that can make a COM interface to the Access object library can run the compact and repair procedure like open-source languages:

Python

import os, glob, shutil
import win32com.client

# LAUNCH ACCESS APP
oApp = win32com.client.Dispatch("Access.Application")

for file in glob.glob("C:\\Databases\\*.accdb"):       
    bkfile = file.replace(".accdb", "_bk.accdb")

    oApp.CompactRepair(file, bkfile, False)

    shutil.copyfile(bkfile, file)
    os.remove(bkfile)

oApp = None

R

library(RDCOMClient)

# LAUNCH ACCESS APP
oApp = COMCreate("Access.Application")

accfiles <- list.files(path="C:\\Databases\\", pattern="\\.accdb", full.names=TRUE)

for (file in accfiles){      
  bkfile = sub(".accdb", "_bk.accdb", file)

  oApp$CompactRepair(file, bkfile, FALSE)

  file.copy(bkfile, file, overwrite = TRUE)
  file.remove(bkfile)      
}

oApp <- NULL
gc()

PHP

# LAUNCH ACCESS APP
$acc = new COM("Access.Application", NULL, CP_UTF8) or Die ("Did not instantiate Access");

foreach (glob("C:\\Databases\\*.accdb") as $file) {            
    $bkfile = str_replace(".accdb", "_bk.accdb", $file);

    $acc->Application->CompactRepair($file, $bkfile, false);

    copy($bkfile, $file);
    unlink($bkfile);    
}

$acc = NULL;
unset($acc);
