华为交换机删除flash里的文件

<S5700>delete huawei.txt?
Delete flash:/huawei.txt?[Y/N]:y?
Info: Deleting file flash:/huawei.txt.......succeeded.

虽然delete成功了，但是文件并未完全从flash中删除，只是放在交换机flash的回收站中，还是占用flash的资源；

<S5700>dir /all?
Directory of flash:/?

? 1? -rw-????????? 8,514? Mar 04 2015 11:19:43???[huawei.txt]? //还在flash中的回收站中；

哪怎么样彻底删除huawei.txt这个文件呢？

1.如果是在回收站中，执行reset recycle-bin，清空回收站；

<S5700>reset recycle-bin?
Squeeze flash:/huawei.txt?[Y/N]:y?
%Cleared file flash:/huawei.txt.

2.先把回收站的文件恢复之后使用delete /unreserved?huawei.txt

恢复回收站中的待删除文件：

<S5700>undelete huawei.txt?
Undelete flash:/huawei.txt?[Y/N]:y?
%Undeleted file flash:/huawei.txt.

<S5700>delete /unreserved huawei.txt?//彻底删除文件，不能恢复Warning: The contents of file flash:/huawei.txt can?Info: Deleting file flash:/huawei.txt...succeeded.
