How to create empty folder in azure blob storage

Question

How to create empty folder in azure blob storage just like empty folder in tool "Azure Explorer"

Answer 1

Technically speaking, you can't have an empty folder in Azure Blob Storage as blob storage has a 2 level hierarchy - blob container and blob. You essentially create an illusion of a folder by prefixing the file name with the folder name you like e.g. assuming you want a style sheet (say site.css) in say css folder, you name the stylesheet file as css/site.css.

What some of the tools do is in order to create an empty folder, they create a zero byte blob and prefix it with the name of the folder and then don't show that zero byte blob. If you want, you can do that.

Answer 2

Here's one way to do it with Linux.

az storage blob upload --container-name <container name> --name <folder name> -f /dev/null --account-name <storage account name>

• the file name ends with a trailing slash (e.g. myfolder/)
• the CLI expects a file, so just upload nothing (i.e. /dev/null/)
