華爲網絡設備的配置文件和VRP系統文件都保存在物理存儲介質中，所以文件系統是VRP正常運行的基礎。只有掌握了對文件系統的基本操作，網絡工程師才能對設備的配置文件和VRP系統文件進行高效的管理。
VRP系統是 基於linux開發的，一些命令和linux命令一樣。
一、基本查詢命令
<Huawei>dir //查看當前目錄下的文件信息
Directory of flash:/
Idx Attr Size(Byte) Date Time(LMT) FileName
0 drw- - Oct 22 2018 06:22:51 dhcp
1 -rw- 121,802 May 26 2014 09:20:58 portalpage.zip
2 -rw- 2,263 Oct 22 2018 06:22:42 statemach.efs
3 -rw- 828,482 May 26 2014 09:20:58 ssl***.zip
1,090,732 KB total (784,464 KB free)
<Huawei>
<Huawei>pwd //查看當前目錄，此時屬於flash: 根目錄下
flash:
<Huawei>
二、目錄操作
<Huawei>cd dhcp //進入dhcp的文件夾下
<Huawei>pwd //查看當前目錄
flash:/dhcp
<Huawei>cd .. //返回根目錄
<Huawei>pwd
flash:
<Huawei>mkdir test //創建新的目錄，名稱爲test
Info: Create directory flash:/test......Done
<Huawei>dir //查看是否創建成功。
Directory of flash:/
Idx Attr Size(Byte) Date Time(LMT) FileName

五、配置文件管理
設備中的配置文件分爲兩種類型：當前配置文件和保存的配置文件。當前配置文件儲存在設備的RAM中。用戶可以通過命令行對設備進行配置，配置完成後使用save命令保存當前配置到存儲設備中，形成保存的配置文件。
保存的配置文件都是以“.cfg”或“.zip”作爲擴展名，存放在存儲設備的根目錄下。
在設備啓動時，會從默認的存儲路徑下加載保存的配置文件到RAM中。如果默認存儲路徑中沒有保存的配置文件，則設備會使用缺省參數進行初始化配置。
<Huawei>display current-configuration //查看當前配置
[V200R003C00]
#
snmp-agent local-engineid 800007DB03000000000000
snmp-agent
#
clock timezone China-Standard-Time minus 08:00:00
#
portal local-server load portalpage.zip
……
<Huawei>dis saved-configuration //初始化啓動的設備還沒有保存，此時無保存配置
There is no correct configuration file in FLASH
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]
[Huawei]sysname QYTANG //修改設備名稱爲QYTANG
<QYTANG>save //保存當前配置信息
The current configuration will be written to the device.
Are you sure to continue? (y/n)[n]:y
It will take several minutes to save configuration file, please wait........
Configuration file had been saved successfully
Note: The configuration file will take effect after being activated
<QYTANG>
<QYTANG>display saved-configuration //查看保存的配置文件
[V200R003C00]
#
sysname QYTANG
