Thanks, BradMZ. As far as I am aware, one can edit certain file properties on a computer, but not the date/time stamp (e.g., the "Date Created"), at least in Windows 10. If you know of a way to edit the date/time stamp on a computer, please let us know. And having to rename the files on a computer using a date defeats the purpose of being able to record songs on the fly directly to a USB flash drive connected to the keyboard using the audio recorder or MIDI recorder. If we wanted to use a computer, we could make the recording using a DAW on the computer. The advantage of having the audio recorder and MIDI recorder functions on the keyboard is to enable recordings to be made without having to use a computer.
Having an accurate date/time stamp reflecting when a file is created is important for many reasons (e.g., knowing when a particular version of a recording was made in relation to other versions). It is surprising that the PX-560 would not have this capability. If it doesn't currently, can Casio provide it in a firmware update ASAP?
