c语言，代码可以运行但完成之后相应文件夹下没有文件怎么解决呢？

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
struct Account
{
    char  ID[11];
    char  name[21];    
    char password[7];
    double remain;
};
typedef struct Account Account;
Account account[9999];
int main()
{
    int nownumber=0;
    printf("请输入账号：\n");
    char ID[]={0};
    int i;
    do
    {
        scanf("%s",ID);
        for(i=0;i<=nownumber;i++)
        {
            if(!strcmp(account[i].ID,ID))
            {
                printf("账号已存在，请重新输入\n");
                break; 
            }
        }
    }while(!strcmp(account[i].ID,ID));
    printf("请输入用户名：\n");
    char name[]={0};
    scanf("%s",name); 
    printf("请输入六位数密码：\n");
    char pw1[5]={0};
    char pw2[5]={0};
    scanf("%s",pw1);
    printf("请再次输入密码：\n");
    scanf("%s",pw2);
    while(strcmp(pw1,pw2))
    {
        printf("！！！密码错误！！！\n");
        printf("请输入六位数密码：\n");
        scanf("%s",pw1);
        printf("请再次输入密码：\n");
        scanf("%s",pw2);
    }
    int IDnumber=nownumber;
    strcpy(account[IDnumber].ID,ID);
    strcpy(account[IDnumber].name,name);
    strcpy(account[IDnumber].password,pw1);
    account[IDnumber].remain=5000;
    char path0[]="D:\\ATM\\Account_information\\";
    char path[]=".txt";
    char finalpath1[]={0};
    char finalpath2[]={0};
    char finalpath3[]={0};
    sprintf(finalpath1,"%s%sname%s",path0,account[IDnumber].ID,path);
    sprintf(finalpath2,"%s%spassword%s",path0,account[IDnumber].ID,path);
    sprintf(finalpath3,"%s%smoney%s",path0,account[IDnumber].ID,path);
    FILE *fp;
    fp=fopen(finalpath1,"w");
    fprintf(fp,"%s",account[IDnumber].name);
    fclose(fp);
    fp=fopen(finalpath2,"w");
    fprintf(fp,"%s",account[IDnumber].password);
    fclose(fp);
    fp=fopen(finalpath3,"w");
    fprintf(fp,"%f",account[IDnumber].remain);
    fclose(fp);
    nownumber++;
    return 0;
}

运行这段代码之后，输入的姓名密码等信息电脑里面没有保存是为什么啊？是哪里出错了呢？谢谢！！

没看见你有保存的语句啊

你printf是写入内存里了
最后你要执行save保存到文件啊
