title: How to copy only files from many subdirectory under the directory to another project bucket in GCP?
body: <p>I have huge number of data in my Google Cloud storage bucket. I have to copy all the files to another project bucket. But the main problem is, in this bucket i created some folder and under this folder have many sub-folders and all sub-folders have data. So when i am using normal gsutil copy command then its copying all the data along with folders.
  I need help to resolve this problem. Because it is taking too much time to copy from one project to another project bucket.</p>
