What is the difference between cFosSpeed and cFos?

• Which product to choose?

cFos/Professional is a Dial-Up driver for DSL and ISDN. You can use cFos with the Windows Dial-Up Network to establish connections to the Internet.

cFosSpeed is a network driver, which attaches itself to existing Internet connections. It then optimizes data transfer by means of Traffic Shaping.

Thus, while the Traffic Shaping technology implemented in both programs is essentially the same, cFos and cFosSpeed are still different products, meaning a license for one product does not cover use of the other (and vice-versa).

If you are running both cFos and cFosSpeed on your system, cFos Traffic Shaping will be deactivated (in favor of cFosSpeed Traffic Shaping).

How can I change the Outlook Express settings, to receive the license key files key.cfosspeed or key.cfos?



Using Outlook Express please go to Extras - Options an then to the submenu Security.

1. Mark Internetzone (useful, but not that safe) with a dot.
2. Disable 'Show warnings'
3. Disable 'Not allow to safe attachments that could be a virus'

Then you can double click the attachment and save it to your disk.

If you need them you can change the settings of the Securityzones again.
