###Directory Structure app/ This is the folder where you will work most of the time. It contains your model, view and the controller. app/model Contains all your models for your project.

app/view	 Includes all HTML files inside a folder. These files are named after an corresponding action inside your        
             controller. Additionally, these files are grouped into folders with the controller name.

app/controller	Holds the logic for your Rails application.

db/  	 All database related files go into this folder. If you are working with SQLite, then the database is 
             likely to be in this folder as *.sqlite3 file.

db/migrate	 Has all the migrations that you created.

config/	 As the names suggest, it has all the necessary configuration files of your Rails application. There is  
             only very little configuration needed, so no worries that you have to crawl through endless lines of 
             code. Localizations, routes and all basic files can be found here.

public/	 All your static files (files that do not change dynamically) your CSS or JavaScript files are inside this 
             folder.

public/images All your static Images

public/javascripts When you embed Javascript, CSS or images, the default location is inside these folders. Rails will 
                  automatically look inside these to find the proper file. 

public/stylesheets	When you embed CSS, the default location is inside this folder. Rails will automatically look 
                    inside this to find the proper file.

script/	Holds scripts for Rails that provide a variety of tasks. These scripts link to another file where the 
           "real" files are. Inside these folder you will find the generators, server and console.

log/	Log files from your application. If you want to debug some parts of your application you can check out 
            these files.

test/	All files for testing your application.
doc/	Documentation for the current Rails application.
lib/	Extended modules for your application.
vendor/	Whenever you have 3rd-party plug ins, they will be found in this folder.
tmp/	Temporary files
README	Basic guide for others on how to setup your application, what specialities it has or what to be careful 
            about.
Rakefile	Handles all the Rake tasks inside your application.
