The File Locations page of the Options window (accessible from the Tools, Options menu item) contains general settings of the program.
Override Settings folder

to select an existing folder. By default this option is set to the "Application Data\Softland\Backup4all 3\" folder of your Window login account profile.
Override Initialization folder
This is the folder where the initialization files are saved. You can use the Browse button to select an existing folder. By default this option is set to the "Application Data\Softland\Backup4all 3\IniFiles" folder of your Window login account profile.
Override Catalog folder
This is the folder where the cached catalog files ("*.bkc") are saved. You can use the Browse button to select an existing folder. By default this option is set to the "Application Data\Softland\Backup4all 3\BkcFiles" folder of your Window login account profile.
Override Log folder
This is the folder where the log files are saved. You can use the Browse button to select an existing folder. You can change the folder, but the existing log files will not be copied to the new location (you can do this manually, if you wish). You can use the Browse button to select an existing folder. By default this option is set to the "Application Data\Softland\Backup4all 3\Logs" folder of your Window login account profile.
Override Default destination folder
This is the folder used as destination for the newly created backup jobs. The existing backup job destinations will not be affected if you change this option (you have to manually change the destination for them). You can use the Browse button to select an existing folder. By default this option is set to the "My Documents\MyBackup4all 3\" folder of your Window login account profile.
Override Temporary folder
This folder is used by the compression engine to handle compressed files (.zip). Only a full path is allowed. The recommendation is to set the temporary directory on the hard disk partition with the most free space available. You can use the Browse button to select an existing folder. By default the option is set to the operating system's temporary folder.
