Hi, this option was checked. Due to the network domain migration I've discovered that ImgBurn might get confused and/or unable to retreive subfolders information (even if the user permissions are ok). A clean uninstallation and then an installation from scratch have solved the problem. Regards, M.
ImgBurn 18.104.22.168 introduced this bug: can't add folders to the source list. If I add a folder which contains file and/or subfolders, I can see the root folder on the source list but empty (it won't be burned). As attachment the error message if I press the "Calculate Image size" button (the 'audio' folder contains actually more then 1GB).
