Conversion of adp files to accdb file format

It looks like that the only way to convert .adp files from Microsoft Access to .accdd files, would be to use some of the later versions of Access that does support .accdd files. When your .adp file is opened using MS Access, you can simply use File ► Save as.. function to re-save your databases to ACCDB format.

No other program can probably help you with adp to accdb conversion, as MS Access formats are proprietary and not well supported in 3rd party software.
