(CkPython) Azure Storage: Upload Binary Data to Block BlobSample code to upload binary bytes to a block blob in Azure Cloud Storage. This creates the block blob, or replaces an existing block blob. Note: The maximum size of a block blob created by uploading in a single step is 64MB. For larger files, the upload must be broken up into blocks. There is another Chilkat example for that..
