Can I write a file in Vercel?

I have already read these docs: Vercel Blob

However, I’m wondering if I can store my file in mywebsite.com/myfiles/myfile.csv OR with Vercels blob approach if I can only store them like that: https://1sxstfwepd7zn41q.public.blob.vercel-storage.com/myfile.csv

I’m using a module which can only read locally (from mywebsite.com/myfiles/myfile.csv

Is this possible with Vercel?

Build file system is read only file often expensive. We would definitely recommend using Object storage such as Vercel Blob, S3 and similar.
