Greetings,

>From what I have encountered, Fat32 does not allow file sizes larger
than 2 GB to be written to it and fat16 allows 4 GB I believe.

I was trying to render out some video from an old Adobe Premiere file
on a Fat32 formatted firewire drive and finally as a consequence of
the file size limitation had to render the file to another drive. I
can see how for smaller flash drives this is a non-issue, but for
drives larger than the fat32 32 GB capacity limitation it is not
suitable and for video work -- therefore stay away from the fat32
standard for larger drives unless you are rendering out everything to
tape or another drive.

If one was recording dawn choruses with 4 channels of audio at 48kHz
-16 or 24 bit rates, FAT 32 may be a disappointment if you wanted an
hour or more, but for smaller file sizes and shorter recordings on
flash drives within the file size limit I guess it could be fine.

Best regards,

Jeff Daub
