Getting Clear read only status on Webstorm 8

I had similar problem and I ran following command and my problem was resolved:

sudo chown -R $(whoami) my-project-folder

Works on both Ubuntu & OS X

To check username use: whoami

Same answer as above but use the current user and also add the files to the current group

sudo chown -R $USER:$USER my-project-folder

$USER is a variable which stores your currently logged in user,at least on Ubuntu.
