I imported a font and images (png) in project's folder Files (with Construct 2). In this folder Files, I made subfolders to tidy up a bit.
Maybe I'm wrong, but I understand the "/media" when exported is for these files. But when I export, I've got no /media folder, which means my 250 png and the font (+css) are on root, mixed with application files. It's not really handy when I need to upload a new version, without uploading images.
