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 4.x, Jetcomp.exe 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.
Note The user interface of JETCOMP.exe is in English only and is not supported by Microsoft Product Support Services. However, JETCOMP.exe can compact databases in any language supported by the Microsoft Jet database engine. JETCOMP.exe is a freely distributable utility, but requires that one of the following products is installed on the computer:
Note You must make sure that no users are accessing the database before you run JETCOMP.exe.
