So I requested a world from a discontinued MC server, and the file is seperated into “world_the_end” “world_nether” and “world”

the world folder has every file except “Dim-1” and “Dim1” Which are in the former two. The two files also have data folders like in the “world” folder which IDK what to do with, so can someone help me through this?

On a side note, is it possible to fix a “crc” error on one of the region files?
