How to upload files to custom folder in AppEngine with blobstore and google cloud storage

I am using Google AppEngine. I am using the blobstore to upload files to Google Cloud Storage. (I can't upload to Cloud Storage directly because of request size restriction of AppEngine.)

I could upload to Google Cloud Storage. But I couldn't specify the folder to upload. So every file is being stored in the root folder.

Can anybody tell me how to upload to a specific folder?

I use the code from https://github.com/crhym3/java-blobstore-gcs-sample

did you try to set .withGoogleStorageBucketName with bucketname/folder value? – Igor Artamonov
ok, that was just in case it works :) – Igor Artamonov
sorry, the 400 was with something else. now it works. If you put it as an answer I could accept it. Thank you very much – Harikrishnan
"I can't upload to Cloud Storage directly because of request size restriction of AppEngine" - You can upload files up to 5GB in size to Cloud Storage directly. App Engine has nothing to do with direct uploads. – Andrei Volgin
but inorder to do direct upload, we need to provide security headers and other things right (authorization)? I want to upload without any explicit authorization from user. – Harikrishnan

It comes out that you can pass a "folder" name with a bucket name into .withGoogleStorageBucketName() method, like:

UploadOptions uploadOptions = UploadOptions.Builder
     .withGoogleStorageBucketName("bucket_name/folder_name");
