I’m confused and I didn’t find any answer by Googling. My theme files such as single.php or header.php reside in a folder. Should I use dashes or underscores in the folder name? My web server run on Linux / Apache and I’m not sure what the consequences are regarding folder names. So should I prefer something like

my_wordpress_theme_folder

over

my-wordpress-theme-folder

or are both equally valid?
