The leading 'a/' is the directory I backuped my wallet files. It's not the problem.
I now successfully dumped a lot of data into a output file using this command:
python pywallet/pywallet.py --wallet=/Users/dong/.protoshares/wallet.dat --datadir=/Users/dong/.protoshares/ --otherversion=56 --dumpwallet >> ~/Desktop/wallet-recovery3.txt
I'm not sure this 'wallet.dat' file has anything to do with the address I sent my PTS to.
In the dump output file, however, I cannot find the address information for the particular address I sent all my PTS to. Is it because I haven't ever used that fresh address to send out PTS? Where does all these address information saved? I noticed there are several db files. What are they?
