Hi @Rajeev z ranjan,

Did the above help you?

I also just now learned that you can send HEAD requests to the download urls, like this:

def get_content_lengths(client, external_ids):
    urls = client.files.retrieve_download_urls(external_id=external_ids)
    return {
        external_id: client.files._http_client.request("HEAD", urls[external_id]).headers["Content-Length"]
        for external_id in external_ids
    }

This might be a workaround if the files for some reason are not available in the documents API. If they are in the documents API, this should require the fewest requests. 

Hi,
You can get the size using the Documents API. List documents gives you the size (in bytes) in `sourceFile`.`size`. 
You can also use the Python SDK. https://cognite-sdk-python.readthedocs-hosted.com/en/latest/documents.html#cognite.client._api.documents.DocumentsAPI.list
Example code:
 

from cognite.client.data_classes.documents import DocumentProperty
from cognite.client.data_classes import filters

file_id_filter = filters.Equals(DocumentProperty.id, YOUR_FILE_ID)
doc = client.documents.list(filter=file_id_filter)
doc>0].source_file.size

Hi!

I cant see that the API has a way to get the file size without downloading the file. 

It seems like a very useful feature to have though. 
If this is a one time cleanup job, it would maybe be ok, though time consuming to do len(client.files.download_bytes(file_id=file_id)) for all the file ids?
