Automating conversions is seldom a good idea: if nothing else, you still
need to test each database to ensure that it works in the new version, so
that the actual time required to open the database in the new version and
have it convert is an insignificant amount of time overall.

While I know you say you're using Access 2002, you might still benefit from
the Access 2003 Conversion Toolkit (since, by default, both Access 2002 and
Access 2003 use the same Access 2000 file format)

Code it yourself.

You can use DIR, or an API call, to loop through a directory or a set
of directories.

You can use the following tool to help you convert MDB from A97 to
A2002.

Then you can use some code on the references to clean up the useless
items such as the VBIDE or the OWC.

Dim ref As Reference

   For Each ref In Access.References
               If ref.Name = "VBIDE" Or ref.Name = "OWC10" Then
                   References.Remove ref
               End If
   Next ref

Then see if it will compile

       Call Access.SysCmd(504, 16483)
