Is there a way I can add files to SoloLearn so that I can display them in my codes?

Question

I've looked for the app folder on my smartphone, but I wasn't able to find it, please help me

Answer 1

Was the problem on:
That you couldn't find a file or a folder from the program?
I have a program that could help for that.

Or:
That you can't display a file in program?
I've seen someones used dropbox to get their images displayed on their web programs.

Answer 2

I guess I have to put the file (audio, video or image) in the same folder as the .html file and then find them with something like src="name-of-the-file.format", but I can't find the folder where my .html files are (the ones I created on SoloLearn).
