I uploaded a firmware file via the GUI which couldn't be assigned as a primary or secondary firmware boot. I attempted to assign it as a boot file in the GUI and the file didn't show up in the drop down menu. I then went to the CLI and executed a show flash. I saw the file in the list but noticed that it had a space in the filename. I attempted to delete it and it returned an unrecognized command error. I attempted to assign it to the primary or secondary boot and it returned and error both times.
I either need to delete the file and upload a copy without a space in the filename or I need to rename it. I need to free up this disk space. Can this be done?

To erase the file, issue the following command:
erase flash "NV3448A-R10-3-0-E (1).biz"
simply place the filename within quotes.
