Does this mean you are moving your 'cold storage' wallet file to your online pc to make a transaction?
This should be avoided under all circumstances!
Private keys of a
cold wallet are supposed to stay offline
all the time.
To spend from a cold wallet you have to create an unsigned transaction (on an online machine), move it to your offline pc, sign it, move it to your online pc and broadcast it.
Or, use a hardware wallet.
But do NOT consider a wallet which you move to an online computer occasionally as a cold wallet.
