new PC to find large folder moved to other folder.Create new folder on 750nvme to install LR?

Hello everyone I think I'm in the correct place for this. I built a new PC and I'm hoping to find a very large folder that was moved by mistake to other folder on hhd that only has pics..is that the cure?My new pc has win 10 pro64 on ssd ,,after reading adobe forums,it seems its best to have OS on ssd and LR6 (I have dvd) and PS CS5(new disc from years ago) on the intel 750 nvme because win 10 is used/sits in ram(I have 32gig).I have not found much about install/configuration details of LR6 to secondary drive 750 nvme while OS is on ssd accept to create a new folder on 750..So are there any tutorials for LR6 from the get go for intel 750 and Whats a really good dvd burning software that works with 4k monitor thank you
