You want to write to two files instead of one?

Make it a function that takes in the filename as a string, and then call it twice with both filenames.

void save_item(const std::string& filename) // change to const char* if not using C++11
{
    fI.open(filename, ios::out|ios::app);
    // ...
}

save_item("list.dat");
save_item("list.txt");

I also suggest making your file stream (fI) be a local variable instead of a global/class variable.

PS: Your function name is misleading. Usually, you should follow the "Do One Thing" or "Single Responsibility" rule. If your function is called "save_X", you shouldn't also be asking for user input in that function. You should only be doing saving.
