Oops, I meant to say there is an option to turn case-sensitivity ON, but 
hardly anyone uses it.


By the way, Linux users can experiment with case-insensitive file 
systems provided they have privileges to mount file systems. Here's an 
example. At the shell:


# allocate 100K for a (tiny) file system
dd if=/dev/zero of=fat.fs bs=1024 count=100

# format as FAT-12 with an optional label
/sbin/mkfs.vfat -n "FAT image" fat.fs

# mount it and create some files
sudo mount -o loop  fat.fs /mnt
sudo touch /mnt/{lower.txt,UPPER.TXT,mIxEd.TxT}


Now you have a file system and some empty files to experiment with.
