Let's say you want to reference custom fonts from .css files and you don't know where to place fonts in pcMobile.
In this case good way to go will be (%PCMOBILE_HOME% is the directory there pcMobile installed, by default is "C:\Program Files (x86)\pcMobile"):
- create subfolder, for example "fonts" for your custom content in "$PCMOBILE_HOME\store\settings\includes\fonts"
- place your content inside folder, let's say it is $PCMOBILE_HOME\store\settings\includes\fonts\myfont.otf
- you can access your file with URL http://localhost/content/includes/fonts/myfont.otf so it can be references from css like "/content/includes/fonts/myfont.otf"
