I'm using laragon in a windows 10 machine for a 2.2.3 Magento install. What folder permissions do I have to set?
By default, all folders are read-only (or so it seems). Currently, I set writable folders (and files): /var/ /pub/media /pub/static
Check the below link it will help you out https://devdocs.magento.com/guides/v2.0/install-gde/prereq/file-system-perms.html
You can give write permission by running below command in your CLI.
takeown /F <folder name>
takeown /F C:\wamp\www\Magento\www\pub\static
I hope so below link is use full for you.
