Hi i have a usb harddrive that is formatted to fat32 but it accepts and plays files bigger than 4gb. Fat32 isn't supposed to take files bigger than 4 gb ? i have another hd formatted to fat32 and that won't so why does the other one ?

Sure you didn't format as exFAT? The bigger,shinier,'nothing else can handle it so you're locked into Microsoft' version of FAT.

Hi i have realised it is only AVCHD files that are being read these are bigger than 4 gb but all other files over that size won't play. Is this right for AVCHD ? i have only used them once before the other day.

AVCHD allows files to be split into chunks, typically just smaller than 2Gb specifically to get round FAT file size limits. Your 10Gb movies are probably actually stored as 5x2Gb files.
