Begin uploading a file in multiple parts. This allows uploading files larger than 5GiB. Note that the size of each part may not exceed 4000MiB, and the size of each part except the last must be greater than 5MiB.

The file chunks may be uploaded in any order, and in parallel, but the client must ensure that the parts are stored in the correct order by uploading each chunk to the correct upload URL.

This returns a context object you must enter (using the with keyword), then call upload_part on for each part before exiting.

Parameters

name (str) – Name of the file.
parts (int) – The number of parts to upload, must be between 1 and 250.
external_id (str | None) – The external ID provided by the client. Must be unique within the project.
source (str | None) – The source of the file.

labels (Sequence[Label] | None) – A list of the labels associated with this resource item.
geo_location (GeoLocation | None) – The geographic metadata of the file.
source_created_time (int | None) – The timestamp for when the file was originally created in the source system.
source_modified_time (int | None) – The timestamp for when the file was last modified in the source system.
security_categories (Sequence[int] | None) – Security categories to attach to this file.
overwrite (bool) – If ‘overwrite’ is set to true, and the POST body content specifies a ‘externalId’ field, fields for the file found for externalId can be overwritten. The default setting is false. If metadata is included in the request body, all of the original metadata will be overwritten. The actual file will be overwritten after successful upload. If there is no successful upload, the current file contents will be kept. File-Asset mappings only change if explicitly stated in the assetIds field of the POST json body. Do not set assetIds in request body if you want to keep the current file-asset mappings.

Returns

Object containing metadata about the created file, and information needed to upload the file content. Use this object to manage the file upload, and exit it once all parts are uploaded.

Return type

FileMultipartUploadSession

Examples

Upload binary data in two chunks

>>> from cognite.client import CogniteClient
>>> client = CogniteClient()
>>> with client.files.multipart_upload_session("my_file.txt", parts=2) as session:
...     # Note that the minimum chunk size is 5 MiB.

...     session.upload_part(1, " world")

Retrieve download urls

Get download links by id or external id

Parameters

Download files to disk

Download files by id or external id.

This method will stream all files to disk, never keeping more than 2MB in memory per worker. The files will be stored in the provided directory using the file name retrieved from the file metadata in CDF. You can also choose to keep the directory structure from CDF so that the files will be stored in subdirectories matching the directory attribute on the files. When missing, the (root) directory is used. By default, duplicate file names to the same local folder will be resolved by only keeping one of the files. You can choose to resolve this by appending a number to the file name using the resolve_duplicate_file_names argument.

Warning

If you are downloading several files at once, be aware that file name collisions lead to all-but-one of the files missing. A warning is issued when this happens, listing the affected files.

Parameters

directory (str | Path) – Directory to download the file(s) to.
id (int | Sequence[int] | None) – Id or list of ids
external_id (str | SequenceNotStr[str] | None) – External ID or list of external ids.
keep_directory_structure (bool) – Whether or not to keep the directory hierarchy in CDF, creating subdirectories as needed below the given directory.
resolve_duplicate_file_names (bool) – Whether or not to resolve duplicate file names by appending a number on duplicate file names

Examples

Download files by id and external id into directory ‘my_directory’:

>>> from cognite.client import CogniteClient
>>> client = CogniteClient()
>>> client.files.download(directory="my_directory", id=[1,2,3], external_id=["abc", "def"])
