Unable to download file from google cloud storage with it's original name.

[Nagaraju Devisetti]

I am uploading the files to sub folders for identifying specific user files, but here file is downloading with path. 
I didn't find any solution for this.

Folders are used to help organize objects in the Cloud Storage, they do not actually exist in a hierarchical structure. Since the objects do not exist in subdirectories, the name of an object is the object name as well as the path to access the object. Depending on the method of downloading objects[3] you can rename the object to the desired name once it is downloaded, or to simply save it as the desired name to begin with.

I have tried this but unable to download more than 30 mb file.

There isn’t a Cloud Storage limit of 30 MB for downloading objects so downloading directly from Cloud Storage should not limit the download size to 30 MB. If you are downloading from App Engine there is a 32 MB limit so download the files from Cloud Storage to avoid this issue.

I am getting Read-only file system bug with cloud storage.

Most probably the issue is that your code may be using the open method, which sets the mode default to read-only.

Less likely, you are trying to save the file to the App Engine file system, which is a restriction documented here. App Engine sandboxed environment does not allow you to save in the file system.
