Azure Cloud Shell File Share Contains 5GB IMG File

Question

I created a PowerShell cloud shell in Azure portal, configured to use an existing general purpose v2 storage account. Created a new file share and gave it a name. When I look inside the file share, I can see a folder ".cloudconsole" with one file inside "acc_[name].img". The size of the file is 5GB.

Question:

1. What is this ".img" file for?
2. Will there be cost associated by having this file in the storage account?

Answer 1

The cloud shell needs Azure File Share to act as clouddrive that store file. So it will ask you create storage account when you use cloud shell.

And the ".img" file is an image of a computer that it works for the cloud shell, and it's free. It just costs for the storage account. You can get more details here.
