# removePipelineItemFile

Detach one file from a pipeline item by fileId (fileIds come from listPipelineItemFiles). This removes the link only: the underlying stored file/bytes are not deleted. Removing a file that is not on the pipeline item, or already removed, is a no-op. Returns the pipeline item id. The pipeline item must be in a pipeline owned by or shared with your organization.
