如何确定ParentFolderId

Question

如何确定ParentFolderId用于放入文档的内容？我通过API下载另一个文档并查看其数据找到了我的数据，但我希望有更好的方法。

var credentials = new BasicAWSCredentials(accessKeyId, secretKey);

var workDocsClient = new AmazonWorkDocsClient(credentials, RegionEndpoint.USEast1);
var uploadRequest = new InitiateDocumentVersionUploadRequest
                {
                    Name = item.File.Name,
                    ContentType = "application/octet-stream",
                    ParentFolderId = ""//How to determine what goes here?
                };

// Exception here
var uploadResult = workDocsClient.InitiateDocumentVersionUpload(uploadRequest);
