And then it looks in a "cross reference" table in, where else but the Registry, to find out what program knows how to read and manipulate that type of file. When you click on a specific file to open it, the operating system looks into the Registry to identify the format that specific type of file is stored in: Image File = bit map, jpeg, ping, dng, etc. Broadly, they can be media files, graphics files, image files, text files, or some other type of file. ![]() When you open a file folder that lives on your desktop, or through the Windows Explorer file navigation program, the operating system identifies when "types" of files are in the folder. These computer files have what might be called an "order of precedence" associated with them in the Registry. Once the Windows Registry gets loaded into memory the computer begins to look for certain types of files on your hard drives and other storage devices that are connected to the computer. Registry conflicts between programs probably cause more problems with Windows-based computers than anything else.Įvery time you turn your computer on, the computer copies the instructions that control the physical devices connected to the computer from a special computer chip on the computer's main circuit board, and then it copies the operating system from the hard drive into the computer's RAM memory and it does this sequentially, in the same order, every time. Windows uses a thing called the "Registry" to keep track of where to find, and how to use this code when an application calls for it. The computer needs these lists and sub-routines to run a given program, and it all gets stored on your computer's hard drive when you install the program(s). These are created when software vendors write program code that conflicts with the program code written by another vendor. The only thing mentioned here that makes any sense to me is similar to what Arjay mentioned with DLL's and software conflicts. ![]() He told everyone he wanted to "upgrade" the accounting and sales computers to this "great new product" that was going to make everyone's life so much "better." I'd already left the Apple stuff behind when Word Perfect came out, and I can't talk much about MacIntosh computers. thanks to the owner of the company I worked for. 3.1 when I was dragged away from the MS-DOS / CP/M operating systems I was perfectly fine running on my computer at home.
