List files

The GET /files operation can be used to return information for all files in a project.

Optionally you can add one or more of the following query parameters. The filter query parameters will filter the results to only include files that match all filter parameters.

Request throttling

This endpoint is intended for data analytics and exploration purposes. It is not designed to support high-throughput data retrieval. Please note that this endpoint is subject to the new throttling policy, which imposes limits on both request rate and concurrency. For more details, please refer to the Files resource documentation.

string (FileName) <= 256 characters

Name of the file.

mimeType
string (MimeType) <= 256 characters

File type. E.g. text/plain, application/pdf, ..

Example: mimeType=image/jpeg
source
string (FileSource) <= 128 characters

assetIds
Array of integers <int64> (AssetIds) [ 1 .. 100 ] items unique

Only include files that reference these specific asset IDs.

Example: assetIds=363848954441724&assetIds=793045462540095&assetIds=1261042166839739
assetExternalIds
string <jsonArray(string)> (JsonArrayString)

Asset external IDs of related equipment that this file relates to. Takes 1..100 unique items.

Example: assetExternalIds=["externalId1", "externalId2", "externalId3"]

assetSubtreeIds
string <jsonArray(int64)> (JsonArrayInt64)

externalIdPrefix
string (CogniteExternalIdPrefix) <= 255 characters

Filter by this (case-sensitive) prefix for the external ID.

Example: externalIdPrefix=my.known.prefix
uploaded
boolean

Whether or not the actual file is uploaded. This field is returned only by the API, it has no effect in a post body.

Example: uploaded=true
partition
string

Splits the data set into N partitions. The attribute is specified as a "M/N" string, where M is a natural number in the interval of [1, N]. You need to follow the cursors within each partition in order to receive all the data.

The maximum number of allowed partitions (N) is 10.

Cognite rejects requests if you specify more than 10 partitions. When Cognite enforces this behavior, the requests result in a 400 Bad Request status.

Example: partition=1/3
