File Management: When to save files to OneDrive or Scotch Central (SharePoint)?

A good way to think about OneDrive storage is that it's for "My files" while Scotch Central (SharePoint) is where we store "Our files".

ONEDRIVE SCOTCH CENTRAL [SHAREPOINT]

OneDrive files are private unless shared with others. That means every file you upload, create, or sync will by default only be viewable by you.
A file or folder can be shared with others in an organisation (Scotch) or with people outside our organisation (e.g., parents).
Once a file or folder is shared, it is viewable only by the file owner and whoever they shared it with.

When files are stored in Scotch Central (SharePoint), they are available to anyone who has permission to access the SharePoint folder.
Real-time collaboration on files
Files cannot be 'shared' with people outside the Scotch organisation.
You can attach a file to an email if you need to share it with an external organisation or copy it to your OneDrive and then share; this will ensure the file located in Scotch Central is not compromised by external parties.
