I recently found out that Skyrim suddenly began to weigh 1TB (these are just numbers, in the end 30GB of space was freed up, but it showed me 1TB and was deleted as 1TB). In the Skyrim folders, the folder with the date was duplicated like a nesting doll 50 times. In each of these folders (almost) there were SKSE and Vortex with all their files. Who knows what the problem is? I want to install vortex again, but I don't want to run into the same problem again. Or maybe I have disk problems? thank you in advance
