To embellish the answer by enzotib ; these players play files in the order they find them in the File Allocation Table (the FAT, in FAT).

FATSort is therefore one potential solution to the problem. The noted warning is for 2 reasons ;

• The tool edits the file allocation table right at the bare metal level
  
  
  
  • It moves the file entries around within the confines of the directory table, so a corrupt filesystem will be more broken than it was before
  
  
  • As long as the filesystem passes a fsck.vfat check, you should be fine.
  
  


• The author appears to feel that he hasn't devoted enough time to making his code secure
  
  
  
  • Potentially, you could create a (broken) file allocation table that caused a buffer overrun or similar problem in the FATSort application
  
  
  • In reality, this is unlikely - it's something of a niche application, the opportunities for an attacker to place a specially crafted file system on your MP3 player are limited, and if he had such an opportunity, there are much softer targets he'd go after first
  
  
  • Again, if your filesystem passes fsck.vfat (or a disk check in Windows), you should be fine - this is a belt-and-braces disclaimer by the author
  
  

palimpsest / Disk Utility has options to do a disk check from the GUI.

Alternate solutions ;

Copy files in the play order

The simplest and most obvious is to copy the files to the player in the order which you wish them to play. Nautilus copies files in an apparently indeterminate order to the player file system for much the same reason - it tends to operate on files in the order the iNodes are arranged on disk.

If your track file names have the track number at the beginning, this is ideal. Most of the command line tools will sort things in lexicographic order. As you note, tools like Midnight Commander will also do this.

# Find the files in the source     | copy them to the target folder

# Note we use the          -print0 |       -0   args because media file names

# commonly contain spaces



find /path/to/music/folder -print0 | xargs -0 cp -t /path/to/target/folder

Create a playlist

Some players support playlist files. I keep scripts in my MP3 player filesystem to support generating these playlists. My player is an iRiver device, which has a specific binary playlist format. If your player supports .m3u playlists, the format is extremely simple, and just consists of commented metadata and paths in a text file. I used to make playlists in Rhythmbox and transform them to the iRiver format ; I've not had occasion to make one using Banshee yet (I only make them for workout purposes and my workouts are very predictable...)
