Hi, I've noticed that in my {steamdir}\steamapps\common\World of Warships\bin\ there are 36 folders e.g. 1874437 1942147 Some of these date back 2 years and are about 100Mb+ for each. I think these are old updates. My Question is can I remove them? If they are not required, you'd think updating to latest versions would remove older versions. thanks in advance

thanks!
