Help needed with the Arduino HP-IL mass storage and 41c

[Klaus Overhage]

No, there is no fix, this behavior used to be normal, only today it is unexpected.

Nowadays file names are always displayed in sorted lists. When I first copied several LIF files to an SD card with my Windows PC, then they were always seen sorted alphabetically. This easily leads to the misconception that the Arduino SD card drive sees it the same way. But the drive sees it like the old DIR command from MS-DOS times. With the help of the command prompt you can try DIR even today. It lists the filenames as they are in the file allocation table FAT without any special sorting in the order they were stored.
