Figure 1. Startup Dialog
If creating a new data file it is recommended to store your .LBK data file in your My Documents/My Logbook Pro Files/v1 folder or a dedicated storage folder such as C:\Logbook Pro Data. Do not store the .LBK file under the C:\Program Files folder structure. After creating a new data file it is recommended to go through each of the tabs in the Options area and configure the settings for Logbook Pro. Configure all aircraft types in the Options...Aircraft area prior to making any flight log entries.
