The heart of otak is the pengkalan.dat file, which is otak’s database. When you want to move data between PCs, or if you want to backup your data, this is the file you want. Everytime you run otak, it will look for this file in the same directory as the otak executable, so all you have to do in the event of a restore is you copy the pengkalan.dat file to the same directory as otak and you’re good to go.
When you upgrade otak and install over the existing otak directory, it will not overwrite your existing pengkalan.dat file (because the installer does not even have the file!). When you run the upgraded otak, it will firstly check the database and add new features and functions automatically.
Backup, Backup, Backup!
As you use otak more and more frequently, you’ll start to rely on it more and more, especially if you start to put in important information that you no longer store anywhere else. If you find that you can’t risk losing anything in otak, then please, BACKUP, BACKUP, BACKUP! Just backing up your pengkalan.dat will do – and store it somewhere safe.
