After upgrading OS to version 7, there is a disk2 folder in the file list. I did not create this folder, I don't know where it came from, but I do know that it cannot be deleted. In version OS6 this folder also appeared but there it could be removed. I also tried to delete it via a terminal, but also without success. Does MiktoTik decide for me what I need more? Is this some kind of bug in the new system?
