1. If this is from theme forest, are you sure its a theme meant for Shopify? Shopify themes have a very strict folder structure. You can see a list of available templates here https://shopify.dev/docs/themes/theme-templates. The screenshot you uploaded doesn't seem to have any shopify theme files. If this theme is meant for shopify, there might be a build step that combines all those files and spits out a proper Shopify theme format (can't tell from that screenshot alone).
