Sometimes when uploading a file to AR router, we will find the free space is not enough. In this case we have to delete some file.
But after delete the file by command:
We will find the avaliable space remains same rather than increasing. so the question is: how to delete a file totally?
When deleting a file by this command:
Actually this file will be moved into recycle bin instead of erasering from Flash.
If we run command:
<Huawei> dir /all
We will find that file still exist in Flash, but marked with "[ ]", which shows it is in Recyle bin.
Directory of flash:/

To eraser them from Flash totally, there are 2 ways:
1. when delete the file, use parameter /unreserved , so that the file will not be moved to recycle bin.
<Huawei>delete /unreserved ar1220-v200r005sph006.pat
2. Use this command to remove the files in recycle bin:
<Huawei>reset recycle-bin ar1220-v200r005sph006.pat
Then the files will be erasered from Flash and the space will be released.
