What are .dll files?

DLL stands for dynamic link library. Everytime a program is opened on your computer, the program will load certain processes into your system's RAM (random access memory). Some programs, in an effort to save RAM, group together like processes into one .dll file. Then, when the program needs to execute a particular process, it can dynamically link the process from this library or .dll into the system RAM.
