If I enable encryption, are the uploaded files encrypted as well?

Hello, Once I enable encryption is everything returned to me as part of form response, i.e. an uploaded W-9 file, encrypted?  Thank You

Here is a snippet from Encrypted Forms and How to Use Them.

Q20: What Happens to Uploaded Files on Encrypted Forms?

They are handled as is, meaning that any file that gets submitted to your form (a photo, document, etc.) is left unchanged and will be passed as is. No decryption or additional handling is required to access or view them.

So, the files uploaded in the File Upload fields are not encrypted.
