c++ - Indexing file names and its content -

-
i write program index file names , content in given directory. if match given regular expression, index them. use regex functions. i don't know how start this. i use polymorphic approach: a class base (virtual), basic information (name, parent directory...). a class file, child of base, represent file. a class folder/directoy represent directory. i thinking using map build trees. may tell me opinion please? for filesystem functionality, use boost.filesystem . for regular expressions, use <regex> c++11, boost.regex otherwise. any initial(!) trouble might have when installing , learning boost pay off. for map, use std::map . in case, not reinvent wheel.
