BIP38 If you have wallets under BIP38, you can decrypt with this https://www.bitaddress.org Then import the private keys on a Bitcoin Cash compatible wallet
Description: Bitcoin Cash is a split from Bitcoin with a protocol upgrade to fix on-chain capacity. If Bitcoin Cash gets majority of PoW then it becomes de facto Bitcoin. It will be a Bitcoin without segwit as soft fork, where upgrades of the protocol are done mainly through hard forks, without changing the economic rules of the Bitcoin. This will be a fork of the Bitcoin blockchain, 1:1, so no-premining, no-ico (it is like a full airdrop)
My opinion: While I support for sure the freedom of choice, you should be wise on touching this kind of things. Your private keys are precious. Keep them safe
