I need a mql folder

`

Dear Developer,

I need a simple mql folder that will carry these features:

1. administrative password: a place kept for user to generate password to protect files that is into the mql folder.

2. password expiring data: after the expiring date the entire file in the folder crashes or deletes all.

3. a single entering of password.   

Note: compactable with mql4 and mql5.
