Question

Quizplus · Accepted Answer

ACCDB is the editable database format used by Microsoft Access, while ACCDE is a locked-down version of the database where forms, reports, and some modules are compiled and cannot be edited. Converting from ACCDB to ACCDE is straightforward, but reversing the process (ACCDE to ACCDB) is not directly possible because the ACCDE format is designed to protect the code and design elements from being modified.
