I wondering why that line was put in the first place with the comment "seems to make it work"

It was added here, but no indication why:

> FileSystemUtils.freeSpaceKb fails to return correct result for a NTFS mount point or
junction.
> Suppose I have a NTFS partition mounted at C:\Data\partition1.
> Now assume that the free space on Partition mounted as C: is 1GB and that mounted on
"C:\Data\partition1" is 2GB. A call to FileSystemUtils.freeSpaceKb("C:\Data\partition1") will
return the free space on C: and not on "C:\Data\partition1".
> This is because while running the "dir /-c" with the given path, the code just retains
first 2 chars i.e. for any path under "C:\blah\de\blah", "dir /-c" will be called with "C:"
which will return incorrect result.
