windows文件去重demo，修改文件路径即可使用

#include <iostream> #include <io.h> #include <direct.h> using namespace std; void listdir(string dir) { string newdir = dir + "\\*.*"; intptr_t handle; struct _finddata_t fileinfo; handle = _findfirst(newdir.c_str(), &fileinfo); if (handle == -1) { cout << "无文件" << endl; system("pause"); return ; } do { if (fileinfo.attrib & _A_SUBDIR) // 如果是文件夹 { cout << fileinfo.name << endl; if (strcmp(fileinfo.name, ".") == 0 || strcmp(fileinfo.name, "..") == 0) { continue; } newdir = dir + "\\" + fileinfo.name; cout << newdir.c_str() << endl; listdir(newdir.c_str()); cout << newdir.c_str() << endl; if (_rmdir(newdir.c_str()) == 0) { cout << "删除空文件夹成功" << endl; } else { cout << "删除空文件夹失败" << endl; } } else { cout << fileinfo.name << endl; char* p = strstr(fileinfo.name, "(1)"); if (p != NULL) { string file_path = dir + "\\" + fileinfo.name; cout << file_path.c_str() << endl; if (remove(file_path.c_str()) == 0) { cout << "删除文件成功" << endl; } else { cout << "删除文件失败" << endl; } } } } while (!_findnext(handle, &fileinfo)); _findclose(handle); return; } int main() { string dir = "D:\\Mini ROS小车附送资料"; listdir(dir); system("pause"); return 0; }
