Problem with tracking events of Copy to Device

[cholv]

I would like to after copy (Drag&Drop) a disk image (flac file) on device was copied cue sheet file.

There are two events: OnDeviceSyncStarted and OnDeviceSyncCompleted, which can be traced up.
But while copying a file, the event OnDeviceSyncStarted for another file does not occur. And I did not find any public event for it.
OnDeviceSyncCompleted is not present copy list. Therefore I must track begin of copy.
OnDeviceFileCopied also does not occur.

Any idea, how can I track a copy of the file on the device while copying another file?
Or how can I track the changes of list to sync?

Thanks.
