你好，boot删文件的话：

1、在boot扩展菜单首页选择输入File Control 对应的编号进入文件控制项(通过文件控制子菜单可以实现显示文件、设置文件类型、删除文件等操作）)：

键入<Ctrl+B>系统进入BootWare扩展段主菜单。

==========================<EXTENDED-BOOTWARE MENU>==========================

|<1> Boot System                                                           |

|<2> Enter Serial SubMenu                                                  |

|<3> Enter Ethernet SubMenu                                                |

|<4> File Control                                                          |

|<5> Restore to Factory Default Configuration                              |

|<6> Skip Current System Configuration                                     |

|<9> Storage Device Operation                                              |

============================================================================

Ctrl+Z: Access EXTENDED ASSISTANT MENU

Ctrl+F: Format File System

Enter your choice(0-9):4         -----------这里

2、输入 Delete File对应的编号

Enter your choice(0-9):4

===============================<File CONTROL>===============================

|Note:the operating device is cfa0                                         |

|<1> Display All File(s)                                                   |

|<2> Set Image File type                                                   |

|<3> Set Bin File type                                                     |

|<4> Set Configuration File type                                           |

|<5> Delete File                                                           |

|<0> Exit To Main Menu                                                     |

============================================================================

Enter your choice(0-5):5   --这里

3、输入要删除的文件对应的序号就行：

============================================================================

|NO. Size(B)   Time                 Type   Name                            |

|1   956       Jan/21/2019 17:59:34 N/A    cfa0:/ifindex.dat               |

|2   24671     Mar/28/2018 09:08:56 N/A    cfa0:/wdydiudie.cfg             |

|3   735       Mar/28/2018 09:18:22 N/A    cfa0:/hostkey                   |

|0   Exit                                                                   |

============================================================================

Enter file No.: 2      --这里

输入文件编号选择待删除的文件，这里以删除编号为2的文件为例，键入数字2，终端显示信息如下：

The file you selected is sda0:/test.cfg,Delete it? [Y/N]

键入<Y>，如果终端显示如下提示信息，则表明文件删除成功：

Deleting.....Done!
