Hi Riccardo,
Thanks so much for sharing your experience with FAT.

I am not a moovies fan but sometimes I record loong audio files, or long 
RF I/Q signals captured by the ham radio SDR receiver for further 
analysis,  that files can easily outpass 2 GB size. So I discard FAT for 
now.

Well, it was a quick test yesterday before going to bed (dissapointing 
test). I always give short file names for my documents, avoiding "í", 
"á" "ü" and strange characters. But some stored files in my 
"/home/ramiro/CRUCIAL_DATA_DIRECTORY" have crazy loooong names. Files of 
downloaded music and also files of stored emails from Thunderbird that 
have the subject as the file name. Perhaps I should clean that names but 
there are something like 1000 files with that issue.

We keep in touch for any discoveries in about this storage sharing issue.
