You need a suitable software like Game Archive to open a WAD file. IWADs contain the data necessary to load the game, while PWADs contain additional data, such as new character sprites, as necessary for custom levels. There are two types of WADs: PWADs and IWADs. WAD stands for Where's All the Data? and the term generally started with the Doom series of games. These are usually packages containing levels, graphics and other game data, and the term WAD is often used to refer to modified versions of these files. The WAD file extension is often used for game archives. When all of the above methods have failed, it remains to contact an IT specialist or developers of the DOOM II program.WAD files mostly belong to Game Archive. In this case, please download or copy the file WAD again. When the file is incomplete, it is not possible to open it correctly.
Check if the file is complete - Sometimes it happens that the WAD file was not copied completely from the external Flash memory, or downloaded from the Internet. Check that the system has the necessary resources to run the Doom II application and open the WAD file. Check if the icon is an element of the correct file but not only a shortcut to the location where the WAD file no longer exists. Check if you, as the operating system user, have appropriate permissions to work with the file WAD. Most often it is disinfection or deletion of an infected file. In this case, scan the WAD file and take the actions recommended by the antivirus program installed on the system. Check if the WAD file is not infected - When the file WAD is infected with a virus or malware, it probably will not be able to be opened correctly. You should then find out what is the reason of the problem. Sometimes it happens that despite having the right application and the correct configuration, there are still problems with opening the WAD files. Check out other possible problems related to WAD files. 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. Finally, select the "Always use the selected program to open WAD files" option and confirm the whole operation. Click "Find more applications on this PC" and indicate the installation location of the appropriate program. Right click on the unknown WAD file you want to open. The second way is simpler and definitely recommended for less advanced users. This can be done in two ways - one is to manually edit the Windows Registry and HKEY_CLASSES_ROOT keys. If the user already has one of the applications installed, the next step will be to associate it with the file extension WAD. Associate Doom II with the WAD file extension
