c++ Recursive renaming of files/directories
Author
I am looking for a way in c++ to specify a directory, and then have it search through it, and all sub directories and rename the directories/files it finds. I found rename() in stdio.h but not sure how to search through each sub directory and file to rename them. Any help or code snippets would be appreciated :)
My implementation is win32 dependent and uses custom stuff (list , text processing)
Here are the main classes that you can use in order to manipulate files and directories , path , etc.
Basic usage:
Path p("directory") or Path p("c:\\home");
Path p(0); - curent path of the file starting with the drive.. eg: c:\blab la\...
PathObject o; represents a file , or a folder;
p.scan(o); - will search trough all the structure starting from path P;
o- now holds the structure of folders and files; with it you can search inside for stuff, get exact location , etc;
Ps: send a PM if you want the rest of the code , there is to much to post it here.
The base code that can get all the files and folders from a folder is:
Node: only one folder , this will not search inside other folders

Boost version:
Actual renaming and matching left as exercise.
#include <boost/filesystem.hpp>namespace fs = boost::filesystem;void recurse(const fs::path & p) { fs::directory_iterator di(p); fs::directory_iterator de; while (di != de) { try { if (fs::is_directory(di->status())) { recurse(di->path()); // fs::rename(di->path(), ....); } if (fs::is_regular_file(di->status())) { // fs::rename(di->path(), ....); } } catch (const std::exception & e) { std::cout << e.what() << std::endl; } ++di; }}int main(){ recurse("r:/root");}Actual renaming and matching left as exercise.

Because the games I do server modding for are done so with c++.
Thanks for the examples :)
