What kind of files does the program consist of and where can they be found?

The program structure consists of three parts:

  • program files
  • program settings file
  • database
Program files

It means the program itself and the files necessary for its functioning. By developing the program and by producing new versions of it the number of these files can be changed. The loss (accidental deleting) of these files does not mean any damage since they can be downloaded from our official website at any time.

The file which stores the place of the database for the program can be found here. It is called AddressBook.exe.config. You can read more about this at "What must the config file include?".

The default place of the files can be found at the path defined by the system:
„C:Program Files (x86)GAS SoftwaresFree Address Book”
It can be varied according to system (32 or 64 bits) and program type (portable or install version can be used)

Program settings

It stores the last settings used by the user like window size, place, and columns to be seen, etc.
Its loss and damage do not mean a big problem. In this case the program overwrites or creates it automatically. However, the user has to set how to arrange its data.
The default place of the file can be found at the logged in user’s directory defined by the system, which is the following for example in case of Windows 10:
„c:Users[ user’s folder]AppDataLocalGAS SoftwaresFree Address Book”


This is the most important part of the program regarded to the user since this file stores data. The loss or deleting of it cannot be substituted. That is why it is very important to create a backup copy the more often it is possible.
Its default place can be found in the user’s folder. You can read more about this at "Where can I find the database file?"

  • The [user’s folder] represented in the path is the name of the logged in user.
  • In case of XP operation system, the Application Data, and in any other cases the AppData folders are hidden folders. For displaying them the ”displaying of hidden folders” option has to be switched on in Windows.
