How many open source file can I use on my project

I want to know how many open source items licensing under MIT, Apache or GNU license can I use in my project?
And also want to know where should I keep the license. Now, I’m put the license text above each js and css fiels, which are taken from open source projects. Is it the correct way to use the license?

I also want to know what is the file structue? Now I’m creating folders named as js, css, fonts, images and keep resources under those folders. Will envato supports this types of file system structure?

Any help will be appreciated. Thanks in advanced.


I would recommend you to create a “vendor” folder inside your project folder and put every third party code you use in a separate sub-folder. And in every folder you include the original source + a license file.
