i was going to write the pun form system 32, but was like... i think this guy its really asking for real, lol.It's an old meme, where ignorant users for some reason feel compelled to clean the IOS's on their systems, even though it literally has no effect on their system performance whatsoever. This led to the dangerous situation of people just randomly deleting critical IOS's from their systems leaving them in a bricked state. If you have to ask what IOS is safe and what to keep your already asking a stupid question and deserve to be mocked. Deleting IOS50 on System 3.4 is the equivalent to deleting the System32 folder in windows.
"Theoretically Speaking, JUST Theoretically" you could delete all IOS, except 80, 58, 236, 249, 250 and 251.
