Hi everyone.

I am trying to write data to file that is outside the dreamfactory dreamfactory/storage and this doesn’t seem to work. Are there particular permissions I need to give dreamfactory. Current the install was done using root.

@Larry_Parker when [installing DF](https://wiki.dreamfactory.com/DreamFactory/APT/Ubuntu_16.04/Installation) we advise the user to set the permission on the storage and cache directories as follows:  
`$ sudo chown -R www-data:dfuser storage/ bootstrap/cache/`  
`$ sudo chmod -R 2775 storage/ bootstrap/cache/`  
I would check that any directory you are writing to has the proper permissions 🍻
