user32355: I lost an old .dat file with 1.5 BTC balance.
I created it with Bitcoin qt 0.8.6, I still have that exact program on my SD card.
I once heard each bitcoin qt wallet does contain a pool of about 100 addresses. Isn't my lost adress supposed to be in that program ? Can I re-generate the adress with that old qt ? If not what can I do ? Nothing I guess...

user13866: You cannot recover control over the Bitcoin amount associated with the addresses in your old wallet data file unless you have a backup of the wallet or a note of the private key.
