Easy2Sync for Outlook stores the tasks and options in configuration files. You can reach these files via the menu item "Tools > Open data directory".
By default the files are stored in this folder for Windows XP:
C:\Documents and settings\<YOURUSERNAME>\Application data\Itsth
For Vista the folder is here:
c:\Users\<YOURUSERNAME>\AppData\Roaming\Itsth
(Caution, the folder c:\Users is invisible. You can reach it by typing the text c:\users into the explorer path line.)
You may also choose a different path for your configuration files. Use the menu items "Tools > Configure data directory".
Backup:
To make a backup of your configuration, simply store a copy of your odb and sdb files in a different folder.
Restore:
To restore a backup of your configuration files, simply restore the odb and sdb files from your backup. Please make sure that Easy2Sync is closed while the files are replaced.
Automatic Backup:
Easy2Sync automatically creates a backup of your configuration files. If a problem occurs with the configuration file, you may use this backup. It is named easy2sync4outlook.backup.sdb and is stored in the same directory as your configuration files.
