DLL File Format

Dynamic-link library file

DLL file format

DLL is a dynamic link library file format used for holding multiple codes and procedures for Windows programs. DLL files were created so that multiple programs could use their information at the same time, aiding memory conservation. It also allows the user to edit the coding of multiple applications at once, without changing the applications themselves. DLLs can be converted to static libraries by using MSIL Disassembler or  DLL to Lib 3.00. The file format for .EXE files are similar to .DLLs, and both types of files contain code, data, and resources.

I'm trying to figure out why there is a .dll file in the place it is supposed to be but the computer keeps telling me I don't have that file at said location

DLL files are all over my computer. I do believe that they are 75% - 80% of all my files on Win 8.1. Could be more. I'm getting my PC ready for the big Win 10 upgrade. Saving what will be gone forever and just cleaning out lots of old crap. If only I knew what was in all those DLL files, should they be saved or thrown out. I'm guessing after reading your commentary here that DLL files are potential bombs, maybe I can get some much needed memory. But then again, I'm a hoarder and scared I'll discard something impertant. There is just so darn many, I know they're stealing my memory. Little grub worms! What to do...
