I have a cisco MDS 9000 series switch with model 9148T 48X32G FC and running 8.3(2) version.
I have a file with a backslash in the boot flash directory
MDS6620C-H25U18# dir bootflash:bootflash/

When I tried to delete this file I am getting the following error:
MDS6620C-H25U18# delete bootflash:v8.1.1a\aaa.txt
^
% Invalid URI path at '^' marker
I tried to connect through WinSCP to connect to the switch to delete it from GUI, but getting the following error to connect from WinSCP to the switch:

Could anybody please suggest to me how to delete the file with a backslash from the switch boot flash directory????
An early reply will be much appreciated.
Thanks in Advance.
