Nothing! (Except for an updated browser)
SharePoint is an internet technology that is accessed from the latest version of the following browsers: Edge, FireFox, Google Chrome, and Safari. No special software is required to use SharePoint. Microsoft 365 also allows you to open Microsoft documents like Word, Excel, PowerPoint, and even Visio on the server, all within the browser. However, to get the full feature set in these documents, Microsoft Office does need to be installed on the client machine.
We recommend the lastest version of Microsoft Edge for use with SharePoint. It has been the most consistent version of any browser so far, and is available for macOS, iOS, and android. For a full list of supported controls and browsers, please visit the Microsoft SharePoint Browser Support page.

Not Exactly
SharePoint is a platform for collaboration. If you use your file share to share documents with your colleagues or house active policies and procedures, then YES! But, if you are looking to archive terabytes of data for safekeeping, this may not be the place for that scenario.
SharePoint does not require you to have Microsoft Office to interact with the platform, and documents can be created and modified in the browser. However, we do suggest having the latest version of Microsoft Office installed to unlock the full capabilities of each application such as Word, Excel, PowerPoint, and Visio.
