The Bitqoin program bitcoin-qt runs ok and obviusly finds the wallet. opening the wallet shows data that is unreadable. Running bitcoin-qt is no problem. Is there a program I can use that can show me the content of the wallet?
The wallet file itself is a binary file format, you will not be able to open it in a text editor and see anything really "human readable"... specifically, it is
Berkeley DB format file. There may be tools that allow you to open and read it, but generally speaking, the only program you
should be using to access this file is Bitcoin Core.
What exactly are you attempting to do with your wallet.dat file? Are you trying to extract the private keys? Are you wanting to get your addresses and/or bitcoin balance without having to sync the whole blockchain?
