bool	operator() (const QFileInfo &left, const QFileInfo &right) const

Detailed Description

This is done by generating "keys" for each string, where each key is an array containing the string split into alpha and numeric parts. For example the string: a123-35abc-15 would become [ a, 123, -, 35, abc, -, 15 ].This key can then be compared piece by piece, ensuring the strings are sorted in a natural way, rather than alphabetically (by ASCII).
