Hi @papithegun, having to do this because :-
1/. You posted problem on a specific site (not general) and only BF4 people can answer you
2/. When I go the your profile I cannot find where to pm you ????
Your ssd is small, especially for Windows 10 and on any hard drive you need to leave about 10% free always regardless, you say you have a 1Tb drive, well pop it in, computer should recognise it as 'D', use 'C' your ssd drive for your operating system only and load other programmes on 'D'. For games you do this at the start, it will ask you where you want to load it, usually something like C/Activision/WAW etc, all you do is highlight the C, change it to D and set it off, it will load that programme on the 1Tb, if you get stuck pm me.
