Here are some notes on the usage of the flash filesystem on the LegoMindstorms NXT controller.

File names can be up to 19 characters long, and are case-insensitive. There is no directory hierarchy; all files are kept in a single top-level directory. The on-board interface shows files grouped into various categories, like “Software files”, “Try Me” etc—these groupings are based purely on the filename extension.

<?plugin OldStyleTable
|*Category* | *File Contents* | *Extension*
| Datalog files | text files containing sensor data | .log
| NXT files| ? | .rpg
| Software files | executable bytecode programs | .rxe
| Sound files | sound sample files; melody files | .rso
| Try Me | executable bytecode programs | .rtm
?>

Filenames ending with other extensions are not visible to the user through the on-board interface, but they can still be accessed programmatically.
