Electron Cash[1] is a lightweight SPV wallet.
Unlike Bitcoin ABC, you don't need to download the whole blockchain before spending your coins.

https://electroncash.org/Electron cash crashes when I try to run the .dat backup wallet file, even if I run it as administrator. What else can I do ?
Do you know which adresses hold bitcoin cash balances? Simply import the wallet.dat in a bitcoin wallet, or where it originially came from, find the adresses that held bitcoin at the time of the fork (and now bitcoin cash), and export their private keys in a bitcoin cash compatible wallet, -- instead of importing the entire wallet.dat... ?
