How to open DUO file?
The main problem with Microsoft Access is that the DUO file is incorrectly associated with programs. Thus, when you open DUO, the program selection wizard or some other program starts. How to solve such a problem?
The first thing you should do is just "doubleclick" on the DUO 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
The first step is to check if the computer has the Microsoft Access program installed. This can be achieved by typing Microsoft Access into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support DUO files.
Programs to open DUO file
Remember to download programs supporting DUO files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Microsoft Access with DUO files
However, it may happen that the application itself does not cause the DUO file to open in the Microsoft Access application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. 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. The "always use the selected program ..." field will set the Microsoft Access application as the default for handling the DUO file.
Step 3. Update Microsoft Access to the latest version
If, despite the association of the Microsoft Access program with the Microsoft Access file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.
Step 4. Check for the following problems with the DUO file
Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:
The DUO file may be unusually small compared to the original file. This is most often caused by a problem while downloading the DUO file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file DUO or the program directory. However, remember that not every infected DUO file can be recovered, so it is important to take care of regular backups.
Older version of DUO file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular DUO file corruption. The easiest way to restore the file is from a backup or by contacting Microsoft Corporation, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted DUO files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the DUO file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file DUO to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
