Answer:
By default, the event log files that record the actions during the import or export can be found in the following folder:C:\Users\Public\Documents\Dlubal\Logs\ImportExport
In most cases, there are several log files in this folder. If you want to open the log of the last data exchange, we recommend sorting the files by the modification date. You can open the logs themselves using an editor or WordPad, for example.
