After Dark Screen Saver Format | Berkeley Systems | Misc Files |
The .AD file is a screensaver file format used by the After Dark, distributed by Berkeley Systems. It was one of the first popular Windows versions of an extensive line of modules and screensavers. This version of American flag screensaver or “Discover America” was a great hit to many fans. It contained many other modules featuring landscapes, planes, animals, stars and various graphics. The modules could be used separately or combined in various combinations, in order to create the desired animation.
Compatibility & Technical Details
The AD files are not compatible with any other platform and require the After Dark software to open them. The files are stored in binary format with data that includes characteristics of the objects used in the composition. To use the After Dark files, users had to install both the program and a folder containing both an.ICN file and a.SYM file.
Other related formats with which users may come across include
- .BSS
- .CAD
- .DSS
- .SAC
Programs for WINDOWS system
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .AD) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .AD extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .AD file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .AD extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .AD extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .AD file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .AD file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .AD file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .AD file) will be extended to the maximum.
It is also good to check
- if the .AD file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
