synchronizing files between Mac and Microsoft Office apps (word and excel)

I'm a Mac user and have many folders and sub-folders organized in Finder. However, I use Microsoft Office for Word and Excel. I've saved many documents into Finder, but updates (and auto-updates) of those files take place in Microsoft. There's no auto-save feature that resides in a file/folder space for a Word document on Finder and it's a hassle to locate numerous documents by heading to OneDrive, which is at least for now a relatively unsophisticated filing system. Is there a way to create an alias on Mac that would point to a file in Word? Or maybe the other way around -- when Microsoft auto-saves a document, is there a way to have that update the file while I'm on Mac?
