 NTFS performs every case-insensitive filename operation — directory
 lookup, attribute matching, indexed binary-tree comparisons — against
 its on-disk **`$UpCase`** table.  That table is a 128 KB flat array

 Windows stores timestamps as **FILETIME**: a 64-bit signed count of
 100-nanosecond ticks since `1601-01-01 00:00:00 UTC`.  Every NTFS MFT
 record carries four of them (created / modified / MFT-modified /
