ELECTRUM.DAT File security

[taiping]

Hi,

I'm using Electrum Windows Installed version.
Is the electrum.dat file stored in Drive C) encrypted?
I'm just wondering about the security of my BTC if someone (say a computer tech) has access to the electrum.dat file, assuming they do not have access to the Electrum 12-word mnemonic code and password for sending BTC.
Thanks for helping.
