The Jet compact utility, jetcomp.exe, is a stand-alone utility
that compacts databases created with Microsoft Jet database engine
3.x and 4.x. This utility may be run in conjunction with Microsoft
Jet database engine 3.x and 4.x for recovering corrupted databases.
Although you can run the Microsoft Access Compact utility or the
CompactDatabase method with Microsoft Jet database engine 3.x and
may be able to recover some databases that these utilities cannot.
The reason for this is that the Microsoft Access Compact utility
and the CompactDatabase method attempt to open and close a database
before attempting to compact it. In certain cases where these utilities
may not be able to reopen the database, Compact will be unable to
proceed, preventing recovery of the database. jetcomp.exe does
not attempt to open and close the database before compacting, and
may therefore be able to recover some databases that the Microsoft
Access compact utility and the CompactDatabase method cannot.
Please backup your database before trying any repairs yourself.
