Thanks for the quick responses guys. I know what to do now to completely delete my information.
It's funny that on this forum people assume that every question is from a newbie. I've had several cold wallets including the Ledger before the notorious data hack, a trezor before it was stolen out of my hotel room and 2 versions of the Bitfi, the latest kept my bitcoin safe but I had to sweep the coins into Electrum as the wallets bricked.
Also if I forget my seed phrase, I'm sure I'll also forget where I stored my super-secret titanium copy. The worst scenario is that I get knocked on the head and forget who I am, but then do my coins mean anything to me. Plus with memorization I can travel world-wide without customs asking me what is this weird little electronic device in my pocket or this note with 12 words on it.
Just sayin'... but thanks for the tips on deleting my files.
