If you are unable to merge an album with one of the albums in the Hi-Res Audio Player, check the following:
- Verify that the album is saved in a single folder. Merging is not possible if the album that you want to merge has multiple sub-folders.
- Verify that the external HDD, where the album you want to merge is saved, is properly connected to the Hi-Res Audio Player.
- If the number of albums you want to merge exceed 99 with a total of 999 tracks, merging will not work.
