The restriction 2GB is a FAT16 limit.
This limit was used for max file size from dos/win 3.x to win millenium, 
2000 and XP because of old hardware and inflexible system administrators 
("Never change a running system"), so FAT and it's limitations survived 
at least within the heads ...

Today large files are possible, but a single file with a lot of needed 
informations within is horrible ...

Most users with mailboxes greater then 1,5 GB are asking me about the 
slow-speeded mail system and some clients (not using thunderbird) 
crashes. So I dont prefer to use storages > 1GB within a single file.
Mostly I use IMAP folders for sorting mails, who the <censored> can 
handle x-thousends of mails within a single folder?
