Does the copy process screw the OGG files up or can you just never overwrite files in the System > Media location and get them to work?
Seems I should just go delete all the ringtones in the System > Media location to remove the dupes and only work from the Internal Storage > Ringtones directory assuming I have all the system ringtones also in the directory.
I used ES File Explorer to copy all my OGG files in system/media/audio to external SD then used Windows explorer to copy the files to my PC. I then did the opposite process to transfer the OGG files off my PC to a new phone (have to mount RW internal storage so ES File Explorer could overwrite any duplicate OGG files.) None of the OGG files I transferred will play. However, the OGG files in the Internal Storage Ringtones directory all play fine and they appear as duplicate ringtones.
