.ACCDE File Extension

Database file created by Microsoft Access, a desktop relational database program; saves a "locked-down" version of an .ACCDB file so that all Visual Basic for Applications (VBA) code is saved in a compiled format and is not viewable or editable; allows custom database code to be protected.

Other functions that cannot be performed in an ACCDE database include modifying forms, reports, and modules.

NOTE: ACCDE files are used in place of .MDE files, which are used by older versions of Access.
