I would copy only the `wallet.dat`; everything else should be unnecessary.  Has your new installation finished syncing with the network?  Have you tried `-rescan`?  Also, was your old `wallet.dat` encrypted?

# Recover Old Bitcoin Wallet (Currently getting a Segfault)

(Asked by: username_0 on 2016-01-12)

I have a bit of bitcoin lingering in an old bitcoin wallet (circa 2011). I just restored it from a backup but I can't seem to load it into `bitcoin-qt`.

If I launch the app, shut it down, the copy in my old `wallet.dat` file and re-open, it shows a zero balance.

If, instead, I shut it down, copy over the entirety of my old `.bitcoin` folder, and then re-open, I get an immediate segfault. How screwed am I?
