The default path where the Olympus Master stores the database with the existing links between photos is C:/ Users/ Your_NAME/ AppData/ Local/ OLYMPUS/ OYMPUS_Data
. Be aware that the AppData folder is hidden by default so you probably want to go to Start and in the search bar type hidden, open the Show hidden File and Folder service in order to check the Show hidden files and folders option, first. After you did this, check the XML file from the path mentioned to make sure that all the links are correct. You can export your photos like before, but don't forget to copy the content of the mentioned folder to your second computer. By doing this, all the links\structures made on the first computer will be available to use on the second one.
