How do we know if a file is encrypted or not via API?

Question

As title, I wonder how can we know a file is encrypted or not via API?

There are a few things you may be referring to, so to address each:

* All Dropbox files are are encrypted at rest and in transit.
* If you're referring to contents of Dropbox "encrypted team folders", the Dropbox API does not return special metadata identifying that, but I'll pass this along as a feature request. I can't promise if or when that might be implemented though.
* If you're referring to additional encryption applied by third party software, the Dropbox system would not be aware of that; the Dropbox system would store whatever data it is sent, whether or not another layer of encryption was added.
