What is a .ADP file?
An ADP file is a special type of file created by Microsoft Access, which is a program used to manage and organize data, like a digital filing cabinet. The "ADP" stands for Access Data Project. This file doesn't store the data itself. Instead, it saves information on how Microsoft Access can connect to and interact with a database stored in Microsoft SQL Server, which is another program for managing large amounts of data but is more powerful and can handle more complex operations than Access.
Think of an ADP file as a bridge between Microsoft Access and a Microsoft SQL Server database. It tells Access how to find the database, how to log in, and how to correctly display the data from that database within the Access program. This is useful for people who want to use the friendly interface of Access to work with data that is stored in the more robust SQL Server environment.
To open an ADP file, you would need a version of Microsoft Access that was released between the years 2000 and 2010. Later versions of Microsoft Access do not support ADP files because Microsoft decided to move away from this format. If you have Access 2000, 2002, 2003, 2007, or 2010, you can open an ADP file by simply double-clicking on it, assuming you have Access installed on your computer. If you try to open an ADP file with a newer version of Access or without having Access installed, it will not work because those versions do not recognize or support this type of file.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
