I would suggest only copy this Dir to USBdrive or whatever you wanna use:
C:\ProgramData\entropia universe\public_users_data (16.8GB)
This Dir is hidden, so you have to disable this option in your explorer settings.
And ofc put the Dir on target drive before running the installer, think this was obvious.
Oh and forgot this is Win10, on Win7 it is somewere else I think.
And in case it will be something like from Win10 to Win7 machine it could probably not work, because of the diff locations the Dir's are in, so not sure if the Dir's are build same between those 2 platforms. (To lazy to go check that atm)
I never tried it before but did read that it should work, I just download it.
Maybe stupid question, but do you have a limit on data on work?
Else just let it download there.
