the lap top suddenly stop working.. computer shop said pc need formating.
the question is
if he did backup for the data before formate will the wallet also be backed up also and i will not lose the data
noted i dont have a back up file for the wallet.
Yes. If you have a complete system backup, you should have the required file.
The wallet information is stored in c:\users\<username>\appdata\roaming\GoldCoin (GLD)\wallet.dat
The "appdata" directory is generally hidden. Google "how to find appdata folder" if you need help.
See if you can locate the file and report back.
