I was just writing an email asking a supervisor about downloading multiple Dynamic-link library files. The acronym for these is dll, and the full spelling, Dynamic-link library, is never used. How would this be pluralized, because normally I would just add an s, but dlls is difficult to understand. Sometimes I add an apostrophe to make it dll's, but I know this isn't grammatically correct. So my question is, how do I make the acronym dll (and acronyms in general) plural?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
"DLLs" is fine. Just capitalize the acronym (it's actually an initialism which makes capitalization even more appropriate/necessary) but leave the plural letters lowercase.
When I reffer to .dll files (or any file extension), I usually add "files" after to avoid confusion as to what a .dll is.
And I add a period before because .dll is a file type.
Just my own convention that works for me.
