Hello, Geez.
Thank you for your reply.
Yes, these files are located there. I deleted the folder and verified the game files but the problem still remains. I mean, I may play peacefully for an hour without having freezes if I downgrade graphics settings to the very lowest ones. Or I may still have freezes that appear after a 30 minutes of gameplay – it's random.
I even created a separate Documents folder on my HDD (where the game is) but the game creates its configuration folder in the default path located on disk C:\. I'm trying to find out what has caused the SSD (C:\) to overload. Will moving the DayZ configuration folder from the SSD to the HDD help to solve the problem? If so, tell me how. If not, please tell me what else I need to do to fix these freezes.
Thank you.

So, I solved the issue by increasing the RAM from 8 GB 2133 MHz to 12 GB 2133-2666 MHz. I still get freezes occasionally but they are not so long and devastating and are mostly related to environment loading that occurs as I travel from one location to another, I guess. The reason that might have caused my SSD to overload could probably be the swap file located on the C: drive. I didn't have the time to investigate this issue further by meddling with the swap file, so I decided to upgrade a bit.
Nevertheless, I had been told that I'd be able to play this game with 8 GB of RAM, as it is indicated in the System Requirements section of your product page on Steam, which I couldn't do even on minimum settings, although all requirements seem to have been met.
Anyway, thank you very much for your efforts to support me.
