What is ADP file?

The file with the extension ADP is the Database Files file type. It was designed by Microsoft. In addition to this file, the Database Files category includes 403 related files. Access Project is supported by 1 operating systems. The file will work on Windows systems, unfortunately not on others. It is recommended to use Microsoft Access to handle this file. This is a program created by Microsoft Corporation. There are also 1 alternative programs to handle the ADP file. You can use Microsoft Office in case Microsoft Access cannot be used.

How to open ADP file?

The most common problem when using Access Project is that a specific ADP is not associated with the program. This is manifested by the fact that ADP files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the ADP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft Access

An often overlooked issue is to make sure that Microsoft Access is installed on the computer. The easiest method is to use the system search engine by entering the program name Microsoft Access in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file ADP with Microsoft Access. Later in this article you will find a list of programs that can open ADP files.

Programs to open ADP file

Remember to download programs supporting ADP files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft Access with ADP files

However, it may happen that the application itself does not cause the ADP file to open in the Microsoft Access application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Microsoft Access application as the default for handling the ADP file.

Step 3. Update Microsoft Access to the latest version

If, despite the association of the Microsoft Access program with the Access Project file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Microsoft Corporation page and install.

Step 4. Check for the following problems with the ADP file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the ADP file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file ADP or the program directory. As a result of the scan, sometimes it is not possible to recover ADP files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of ADP file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged ADP files. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft
When reading, a message appears that the file was encrypted or corrupted. The encrypted file ADP except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move ADP to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the ADP file again. However, some background programs may block the ADP file while scanning. If this does not work either, restart the device.
