What is DMD file?

The file with the extension DMD is the Developer Files file type. It was designed by Oracle. Developer Files consists of 1205 similar files. SQL Developer Data Modeler Format appears on 3 operating systems as a functional file. These systems consist of Linux, Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. The SQL Developer Data Modeler application is recommended to open the file. It was released by Oracle Corporation. This file type can also be opened by 2 other programs.

How to open DMD file?

An often recurring problem with SQL Developer Data Modeler Format is that DMD is not associated with the correct program file. This is manifested by the fact that DMD 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 DMD 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 SQL Developer Data Modeler

In this case, you should first verify that the SQL Developer Data Modeler application is installed on the computer. To do this, enter the name SQL Developer Data Modeler into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open DMD files.

Step 2. Create association of SQL Developer Data Modeler with DMD files

However, it may happen that the application itself does not cause the DMD file to open in the SQL Developer Data Modeler application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the DMD file with the SQL Developer Data Modeler application.

Step 3. Update SQL Developer Data Modeler to the latest version

The fault may also lie with the SQL Developer Data Modeler program, it is possible that SQL Developer Data Modeler Format requires a newer version of the program. In this case, use the Oracle Corporation website or update the program from the application.

Step 4. Check for the following problems with the DMD 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 DMD file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our DMD file. However, remember that not every infected DMD file can be recovered, so it is important to take care of regular backups.
Older version of DMD 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.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair DMD file corruption. The easiest way to restore the file is from a backup or by contacting Oracle, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file DMD 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 DMD to a different directory.
This can happen on a file that does not support multiple access. In this case, the DMD file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the DMD file again. However, some background programs may block the DMD file while scanning. If the problem persists, restart the machine.
