YX5300 player issue with file ordering

[kovalick]

Hi
I appreciate your YX5300 player code. Works fine for me on a Arduino Mega. However, I am having file ordering issues. My files are stored as such on the SD card. Where xxx is ascii text between 10 and 40 bytes long.
001-xxx
002-xxx
003-xxx
004-xxx
005-xxx up to 020-xxx (no missing files, all in order)
When I use the Pnn command, it plays the wrong file. P01 for example plays file #4. There is a 4 increment offset, P010 plays P013 for example. I am using FAT32 and the on the wire data is correct. I see the correct command bytes going to the YX5300 card. Any ideas on what is going on? Thanks Al (Santa Clara, Ca)
