This code snippet shows how to change the content type of Windows Azure blob storage. In some cases, a lot of media files stored on blob are in different formats – mp4, image file, etc. Sometimes, all these files are set as one content type: application/octet-stream, which causes issues in media playback and progress bar. Many users would like to know how to set the appropriate Content-type for files stored on blob (like – video/mp4, video/ogg, video/webm)—not to do it manually for each file through blob interface. This script will help users easily batch change the content type of blob storage. It allows users to change content type of blob storage to any data type.
