查看到flash中有舊版本IOS資料夾

switch#dir
Directory of flash:/

    2  -rwx        1596   Sep 1 2016 14:44:22 +08:00  vlan.dat
    3  -rwx        5465   Sep 8 2016 10:11:30 +08:00  config.text
    4  -rwx        4120   Sep 8 2016 10:11:30 +08:00  multiple-fs
    6  -rwx        4896   Sep 8 2016 10:11:30 +08:00  private-config.text
    7  drwx         192   May 9 2011 13:51:25 +08:00  c2960-lanbasek9-mz.122-46.SE
    8  -rwx     9822428   Nov 9 2016 19:56:25 +08:00  c2960-lanbasek9-mz.122-55.SE11.bin

若一般要刪除flash中的檔案，會執行delete或rmdir
delete主要是刪除檔案非資料夾。
rmdir是刪除資料夾，但資料夾內要為空。

switch#dir flash:/c2960-lanbasek9-mz.122-46.SE/                                
Directory of flash:/c2960-lanbasek9-mz.122-46.SE/

    8  drwx        4800   May 9 2011 13:49:01 +08:00  html
  552  -rwx     7241051   May 9 2011 13:51:25 +08:00  c2960-lanbasek9-mz.122-46.SE.bin
  553  -rwx         533   May 9 2011 13:51:25 +08:00  info

switch#rmdir flash:/c2960-lanbasek9-mz.122-46.SE

Remove directory filename [c2960-lanbasek9-mz.122-46.SE]?    
Delete flash:/c2960-lanbasek9-mz.122-46.SE [confirm]   
%Error Removing dir flash:c2960-lanbasek9-mz.122-46.SE (Directory not empty)

此時我們就可以採用以下命令來刪除一個不為空的資料夾

switch#delete /recursive /force flash:/c2960-lanbasek9-mz.122-46.SE

   /recursive 刪除指定資料夾下的檔案及資料夾 
   /force     刪除並不給出提示

switch#dir
