title: How to change the name of file uploaded to GCS using Bloblstore API
body: <p>I'm using JAVA Blobstore API to upload files directly to the GCS. I have followed this </p>
  
  <p><code>https://cloud.google.com/appengine/docs/java/blobstore/#Java_Using_the_Blobstore_API_with_Google_Cloud_Storage</code></p>
  
  <p>This is working seamlessly. But when I tried to view or download the file, from GCS, its actually showing a different name than I uploaded. Its happening while uploading itself. I think, It takes a random blobkey as file name. </p>
  
  <p>Is there any way to change the filename in GCS after uploading programatically, or any way to upload with custom name using Blobstore API.</p>
  
  <p>Any help would be greatly appreciated. </p>
  
  <p>Thanks.</p>
