How to open DD file?

The most common problem when using Doodle C64 Image Format is that a specific DD is not associated with the program. Thus, when you open DD, 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 DD 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 Norton DiskDoubler

In this case, you should first verify that the Norton DiskDoubler application is installed on the computer. This can be achieved by typing Norton DiskDoubler into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file DD with Norton DiskDoubler. Below you will find a list of applications that support DD files.

Step 2. Create association of Norton DiskDoubler with DD files

If the application is or has been freshly installed, but the DD file still does not use the Norton DiskDoubler program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting 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. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the Norton DiskDoubler application as the default for handling the DD file.

Step 3. Update Norton DiskDoubler to the latest version

If, however, after binding Norton DiskDoubler with Doodle C64 Image Format there were still problems, you should update the program to the latest version.

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

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This suggests truncating the DD file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our DD file. However, remember that not every infected DD file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the DD files changes over time. 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. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged DD files.
The program can also signal the fact of encryption. The encrypted DD files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. If possible, you can try to move the DD file to another location.
This problem only occurs with more complex files. In this case, the DD file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the DD file again. However, some background programs may block the DD file while scanning. If nothing helps, please reset the device.
