1. Variable name
   The name of the variable to copy the data from.
2. Decode base64
   If the data in the variable is stored as an encoded base64 data stream, then you can enable this to convert the base64 data stream into a binary data stream.
3. Resource type
   The Library type of the new resource.
4. Resource path
   The path and resource name to copy to. The path is within the selected resource type.
