Viraj Kamat Thanks for waiting so long on this issue.
After reviewing the issue, I was able to reproduce the same and found that you are using different name than your deviceid for the container folder name.
The files must be uploaded to a folder with the same name as the device ID. This is by design.
Since the IoT Device SDK uploads the files for each device into their own folder and the files view within IoT Central is per device.
If you are following the doc, and files should uploaded by the device SDK under the device id folder in the Storage account.

Configuration of the Device File Storage:
