Password Recovery by HXTT is a free toolkit for MS Access databases from 95, 97, 2000, XP, 2002, to 2003. MS Access uses underlying Jet Database Engine, which is used used in a variety of Microsoft products such as Money, Project, IIS, Exchange, and so on. That freeware can be used for those Jet database files too.
Since MS Access 95, user can set up a single password that controls who can open a database. If there's a database password set, all users have to enter that password to open the database. That freeware can help you to retrieve forgotten database password in MDB password protected files.
This program should work on any platform that supports Java.
