I had installed bitcoin in c:\bitcoin however C disk has run out of space and I moved blocks to other HDD.

bitcoin core does not load wallet.dat that I have stored in c:\bitcoin
Instead it creates new wallet.dat file in datadir (E:\bitcoin)

Is it possible/how to get bitcoin core to load original wallet.dat ?

I really do not wish to just place wallet.dat in E:\bitcoin (unencripted HDD).
