Dim J as new jro. jetengine
'Create and compress the temporary database to another directory.
J. compactdatabase "provider = Microsoft. Jet. oledb.4.0; Data "&_
"Source = D:/mydb. mdb ;"&_
"Jet oledb: Database Password = 123456789 ",_
"Provider = Microsoft. Jet. oledb.4.0; Data "&_
"Source = E:/mydb. mdb ;"&_
"Jet oledb: encrypt database = true ;"&_
"Jet oledb: Database Password = 123456789"

'Delete the original database
Kill "D:/mydb. mdb"
'Copy the compressed database back to its original location.
Filecopy "E:/mydb. mdb", "d:/mydb. mdb"
'Delete temporary database
