I cannot determine where my newly converted files are located. Is there a place to look this up in Media Center 25? Also, if I could figure out how to search for newly created files on the MacBook that would help me also. I'll keep searching the web for answers...
According to this unfortunate article:
https://wiki.jriver.com/index.php/Converter_SettingsI should be able to go to Tools > Advanced Tools > Convert Format > Options > Converter
but on version 25 you can only get as far as Convert Format (Options is not in the menu)
Once you click on Convert Format it says: Please select tracks you want to convert.
Articles on the web that refer to searching for files on the MacBook are also outdated and do not apply to the current software version. It appears that JRiver and Apple are buddies in this regard.
