When I create new Azure function, the specified storage account also create logs and files like host locks. For consumption, plan storage uses File Share to store whole function app by default.
When I want to delete my azure function, nothing is deleted in the storage account.
Storage account after deleted:
On either a Consumption plan or an App Service plan, a function app requires a general Azure Storage account, which supports Azure Blob, Queue, Files, and Table storage. This is because Functions relies on Azure Storage for operations such as managing triggers and logging function executions, but some storage accounts do not support queues and tables.
They are part of a resource group, if you don't delete the whole resource group you have to delete each item seperately.
