Can't delete bin file on ISR4431

[rfountain]

I'm trying to delete an unused bin file on a router I plan on upgrading.  

Directory of bootflash:/

*snip for brevity*

14 -rw- 424196520 Jan 13 2016 14:13:28 +00:00 isr4400-universalk9.03.13.04.S.154-3.S4-ext.SPA.bin
15 -rw- 491568196 Mar 26 2017 23:57:30 +01:00 isr4400-universalk9.03.16.05.S.155-3.S5-ext.SPA.bin

I'm trying to delete the top one [S4] but I get an error:

Router01#del flash:isr4400-universalk9.03.13.04.S.154-3.S4-ext.SPA.bin
Delete filename [isr4400-universalk9.03.13.04.S.154-3.S4-ext.SPA.bin]? y
Delete bootflash:y? [confirm]
%Error deleting bootflash:y (No such file or directory)

I'm not sure why it thinks the file isn't there, I'm looking right at it.

Syntax is wrong.  

Try this: del /f /r bootflash:isr4400-universalk9.03.13.04.S.154-3.S4-ext.SPA.bin
