/*
   Search pattern is of the form:
    - \directory\glob
    - \glob
    - glob (equivalent to \glob)
   The glob part can be for example:
    - *
    - *.txt *.c
    - <.txt <.c
    - >"txt
    - >>>>>>>>">>>
    - >>>>>>>>"TXT
    - >>>>>>>>
    - ?*.TXT
    - ?.TXT
    - file*
    - file.???
    - file"*
    - file
    - file.ext
   The meaning of the glob part varies:
    - Search pattern is cut in two parts analyzed separately:
       + file.ext : file part and ext part
       + file.    : file with an optional extension
       + file     : file with an optional extension
       + .ext     : any file with extension
    - Each part has the same meaning:
       + [empty]  : zero or more characters
       + ABC      : only ABC
       + *        : zero or more characters
       + ?ABC     : one character, then ABC
       + ABC?     : ABC, then one character
       + ABC??    : ABC, then one or two characters
       + ABC????? : ABC, then one to five characters
       + ???????? : one or more characters
    - special characters have equivalents:
       + > = ?  (however, >>>>>>>>.>>> has to be considered as *.*)
       + " = .
       + < = *
