I uninstalled MT4 then reinstalled it but it did not fix the problem, I suspected something was wrong with my Windows so I used a software to repair my Windows called" Repair Professional (All in one) v4.4.6 Portable" and the problem was gone. I think it is a very good software;I strongly ...

My MT4 platform opens normally but when I click File > Open data folder nothing happens ; any idea why ?
It opens when I click File > Open data folder on my MT5 platform but not on MT4.

Does anybody know why ?
