Maximum File Sizes
SharePoint lets you store big things, but it does have its limit.
And to complicate matters, the limits vary between on-prem versions and online.
SharePoint 2013 and 2016 let you upload files as big as 250MB by default.
2013 farm administrators can increase this threshold all the way up to 2GB hard limit.
In 2016, the hard limit is 10GB.
In SharePoint Online, the default limit is 15GB, but in order to upload a file that big, you have to drag the file into the browser.
The good, old fashioned, upload button has a 2GB limit.
