How does sharepoint work?

[Mark M]

A really basic question but could anyone explain how sharepoint works in real life, ideally in a sme/micro environment if possible?

I’m looking for something to replicate a local nas share but have it accessible remotely. Dropbox, or similar, would work but I can’t have 2 people open the same file at the same time and cause a conflict. Files are basic office files and some program specific files.

I had assumed one drive was the same as drop box in that it just syncs data to the cloud which means duplicates can occur?

I think I may have described the wrong thing I’m after but we have small database files for our payroll and accounts software, currently these are stored on a NAS locally. If one person has company A payroll file open then it won’t let anyone else open it. They could be stored in Dropbox etc but when I trialed it people would leave them open and then someone else open the same company file and you’d end up with multiple conflicted versions.

Essentially I want the folders viewable in windows explorer as they are now but with access from home. Currently we log in via Team Viewer but that means I need a computer in the office and a computer/laptop for the staff at home.
