Any softwaire for training openings ?

Hi everyone, 

I wanted to know if one of you would be kind enough to give me the name of software - preferably free - where I can practice openings. I would like the software to be in this form : 

1. I launch the software

2. A directory that I previously created appears like this : 

- Ruy Lopez

- Sicilian Defense

- French Defense

- English opening

- Etc. 

I just have to click on the folder, for example "Ruy Lopez", and there I have to find the best moves on X variations during X moves (I play White and Black / I play only White / I play only Black)

I hope I've been clear and I apologize for my potential bad english.

Thank you very much for your future responses. 

For your purpose Chesspositiontrainer.com is worth a try. You can use all Premium features up to one month for free and then decide if the software is worth its price (39 €). With pgn import you could start fast and with pgn export you don't lose anything you insertet into this software.
