filesystems - root folder equivalent in windows

Question

Is C drive treated as the root folder in windows when one says folder1folder2 in linux and windows C:folder1folder2.

Answer 1

In Windows it's relative to what drive your current working directory is at the time. If your current directory is in the C drive then C: would be the root. If the current directory is the D drive then D: would be the root. There is no absolute root.
