如何使用 C++ 打开 %appdata% 中的文件夹？
#include <windows.h>#include <shlobj.h>
#include <filesystem>
#include <iostream>
int main(void)
{
std::filesystem::path path;
PWSTR path_tmp;
/* Attempt to get user's AppData folder

*/
auto get_folder_path_ret = SHGetKnownFolderPath(FOLDERID_RoamingAppData, 0, nullptr, &path_tmp);
/* Error check */
if (get_folder_path_ret != S_OK) {
CoTaskMemFree(path_tmp);
return 1;
}
/* Convert the Windows path type to a C++ path */
path = path_tmp;
/* Free memory :) */
CoTaskMemFree(path_tmp);
std::cout << path << std::endl;
return 0;
}
TCHAR appdata = {0};
SHGetFolderPath(NULL, CSIDL_APPDATA, NULL, 0, appdata);
