The inbuilt repair utilities Compact utility and Compact Database method in MS Access allow you to perform Access Database Repair in many cases. The Jet compact utility (JETCOMP.exe) is one such recovery utility, which compacts the databases created with Microsoft Jet database engine 3.x and 4.x. This stand-alone utility can recover more databases in comparison to MS Access Compact utility and the Compact Database method because it does not attempt to open or close the Access database before compacting. In case, this utility fails to perform access repair, then the user needs to use effective Access Recovery software.
As a practical example, when a user uses Jetcomp.exe to compact an Access database, he encounters the below error message:
Records can’t be read, no read permissions on MyDatabase.
