Do not know how to trace my Lost Litecoins

Hi there. I have come back to litecoin after a number of years, i have added in my wallet.dat file and when it syncs up it says i have zero in my account. Is there anything i can do. thanks professionals

your backed up wallet.dat file, was done after your transactions right?

also, where is your wallet.dat located?

yes maybe my backed up wallet.dat file was done after my transactions cannot remember it was a long time ago.

I copied it over from an old machine.

my wallet.dat file is located in users/alan/appdata/roaming/litecoin folder

there must be only one wallet.dat file in that folder.

verify that.

yes there is only one wallet.dat file in that folder, it is the one from my old machine

try doing a rescan
