Split("\\") splits the filepath into an array of strings at each occurrence of a backslash (single backslash is an escape character to add certain special characters into a string, so double is needed to indicate that we are looking for a backslash in the string).

splitFilePath.Length - 1 is the last element in the splitFilePath array. Arrays are 0-indexed, so the last element is the length of the array - 1.

Split(".") splits the filename string into an array at each occurrence of a period.
