函数名: rename
功 能: 重命名文件
用 法: int rename(char *oldname, char *newname);
程序例:
#include
int main(void)
{
char oldname[80], newname[80];
/* prompt for file to rename and new name */
printf("File to rename: ");
gets(oldname);
printf("New name: ");
gets(newname);
/* Rename the file */
if (rename(oldname, newname) == 0)
printf("Renamed %s to %s.\n", oldname, newname);
else
perror("rename");
return 0;
}

函数名: remove
功 能: 删除一个文件
用 法: int remove(char *filename);
程序例:
#include
int main(void)
{
char file[80];
/* prompt for file name to delete */
printf("File to delete: ");
gets(file);
/* delete the file */
if (remove(file) == 0)
printf("Removed %s.\n",file);
else
perror("remove");
return 0;
}
--------------------------------------------------------
拷贝的话，
要么字节写一个函数；
或者使用 win API： CopyFile
