How to open SDII file?

The main problem with Sound Designer 2 Audio Format is that the SDII file is incorrectly associated with programs. This causes the file SDII to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the SDII 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 Avid Pro Tools

An often overlooked issue is to make sure that Avid Pro Tools is installed on the computer. The easiest method is to use the system search engine by entering the program name Avid Pro Tools in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file SDII with Avid Pro Tools. Below you will find a list of applications that support SDII files.

Step 2. Create association of Avid Pro Tools with SDII files

If, despite the installed application, the SDII file does not start in the Avid Pro Tools application, you must create a file association. 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. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the SDII file with the Avid Pro Tools application.

Step 3. Update Avid Pro Tools to the latest version

If, despite the association of the Avid Pro Tools program with the Sound Designer 2 Audio Format file, the file still does not open, check the program version and possibly update it to the newest version.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. Usually this applies to SDII files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
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 SDII or the program directory. As a result of the scan, sometimes it is not possible to recover SDII files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of SDII file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair SDII file corruption.
The program can also signal the fact of encryption. The encrypted file SDII 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.
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. Copying the SDII file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the SDII file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the SDII file again. Some anti-virus or backup software may occupy the SDII file for a certain period of time. If this does not work either, restart the device.
