Another standard system issue — again, with Windows-based operating systems — is a DLL error. This means a DLL file is either missing or corrupt. Files ending with “.DLL” are dynamic link library files.

They hold many codes, procedures, and instructions for programs. They exist to tell the OS how to deal with certain apps. Several programs can also open them at once, improving memory conversion.
These are necessary system files, and when they’re missing or corrupt, bad things happen. This is unfortunate, and common because there are so many of them.
