Hi I am having difficulty in getting my SD card to recognise audio wav files. I have copied two MP3 books with no problems and am trying to place some ordinary audio wav books into sub folders within 'other books'. The files are being copied but are not showing in 'other books'. I'm not sure if there is anything additionally I need to do when creating folders for wav files? The User Guide doesn't make it clear. The other thought I had was whether the files were created too long ago to be recognised in vista (1995). Any help much appreciated. Thanks. Wendy
