Subject: Question regarding information in IriverFAQ - FAT32 file size limit

Question regarding information in IriverFAQ - FAT32 file size limit

I was reading through the IriverFAQ
<http://www.rockbox.org/twiki/bin/view/Main/IriverFAQ> and noticed
something. The FAQ says:

-----------
  Will recording in Rockbox have the same filesize limitations as the
Iriver firmware?
No. The file size limit for recording in Rockbox will be 2 GB per
file. (This is a limitation imposed by the FAT32 file system.) Thus,
.WAV recording will allow a maximum of approximately 3 hours 20
minutes per file at 44.1 kHz 16 bit stereo. However, Rockbox has an
automatic file split function, so it will continue recording in a new
file.
-----------

However, the largest file that FAT32 can support is 4 GB, not 2 GB. To
quote microsoft
<http://www.microsoft.com/resources/documentation/Windows/XP/all/reskit/en-us/prkc_fil_cycz.asp>:

"The largest possible file for a FAT32 volume is 4 GB minus 1 byte"

Is this a mistake in the FAQ or is there some other limit that will
prevent a file from getting bigger than 2 GB? I didn't want to edit
the wiki without knowing for sure.
