When you double-click a file to open it, Windows examines the filename extension. If Windows recognizes the filename extension, it opens the file in the program that is associated with that filename extension. When Windows does not recognize a filename extension, you receive the following message: Windows cannot open this file: example.csd. Without proper software you will receive a Windows message 'How do you want to open this file?' (Windows 10) or 'Windows cannot open this file' (Windows 7) or a similar Mac/iPhone/Android alert. If you cannot open your ISTR file correctly, try to right-click or long-press the file. Then click 'Open with' and choose an application.
After double-clicking on the unknown file icon, the system should open it in the default software that supports it. If this does not happen, download and install the CSD Reader software and then manually associate the file with it.
If there is no CSD Reader or similar software in the system that supports files with the CSD extension, you must first download and install it. Below you will find a list of the most-used applications that work with CSD. After going to the subpage of the program you will find a link to the developer's website, where you can safely download the software installer.
If the user already has one of the applications installed, the next step will be to associate it with the file extension CSD. This can be done in two ways - one is to manually edit the Windows Registry and HKEY_CLASSES_ROOT keys. The second way is simpler and definitely recommended for less advanced users.
Remember! Manually editing the system registry is only recommended for advanced users, and changes made to it without proper knowledge may result in damage to the system.
Sometimes it happens that despite having the right application and the correct configuration, there are still problems with opening the CSD files. You should then find out what is the reason of the problem.
