@wendygintz not be default and not easily... and depending on how/where you want to track, it could impact website performance.
In Marketing > Files and Templates > Files you can click any file and see where it's used, and then you could review the page analytics for views (images, not pdfs/links)
For files, if you want to track views you can turn the file link into a CTA, which would give you tracking for when the CTA is viewed, clicked, etc.
This will impact your page performance because it loads the tracking code.
For all links, you could also enable cross domain tracking which would effectively turn all of your links into tracking links, but you wouldn't necessarily be able to analyze this data globally.
I know this isn't the answer you wanted, but hopefully it provides some insights into what's possible.
