Creating a directory in root folder?

Hi! I’m using Open Source Social Network on my site, and it needs a data folder. The problem is that it can’t be in the installation directory (or the htdocs folder). Is there any way I can make a data folder in the root directory? Thank you in advance.

Nevermind. For some reason the permissions were messed up in the root directory and I couldn’t add anything. It’s all fixed now.
