QMF for Windows Administrator installs with a default SDF called qmfsdf*.ini. (where * stands for the version number). You can configure this default SDF for your environment and pass it to your users. If you choose to use this file, you do not need to create a new SDF.
A sample database server, QMF for Windows Demo is already configured in the default SDF. You can use this SDF, the sample database and a TCP/IP connection to learn about the QMF applications.
