I've got a web directory /www along with a folder for the reason that directory known as 'store'.

Within 'store' is several files and folders, I wish to provide the folder 'store' and all sorts of files and folders inside the 'store' folder all permissions.

How do you do that? I'm speculating via .htaccess.

should you opting for the console command it might be

chmod 777 -R /www/store

'-R' causes it to be recursive.

edit - directory added

If by all permissions you mean 777

Navigate to folder and

chmod -R 777 .
