If your files live in a remote service or bucket, you can simply use one of the native Deepnote integrations to access the files. We have integrations with Amazon S3, Google Cloud Storage, Google Drive, Google Sheets, Microsoft OneDrive, Box, Dropbox, and Azure Blob Storage.
Deepnote's integrated file system is intended for small files. The limit for an uploaded file is 100MB and the total limit for a single project is 5GB. If these limits are a problem, we recommend using systems designed for data at scale (i.e., buckets, shared drives, databases, or warehouses). We help by providing a managed storage bucket for you, as well as integrations with S3, GCS, Google Drive, Google Sheets, OneDrive, Box, Dropbox, and Azure Blob Storage.
