I set up an Electrum wallet before I learnt that you should verify the signature. While I went straight to the electrum.org website to download it, I would still like to be secure, just in case. So I want to start again (I had no crypto yet in this wallet).
What should I do to be sure that I have eliminated all the files for the old wallet from my PC (Windows 10), so there is no chance of confusion when I download a second time? I downloaded the Windows Installer version.
