[edit] How max cluster size may be greather than max file size?

Why not? It's not a contradiction. They may very well have designed it that way. Unsound (talk) 04:59, 7 June 2008 (UTC)

No idea, yet it hasn't been updated in Microsoft's Connect site; so unless it's being beta tested inhouse; who knows.. Many beta tester's including myself think that it may be dead. :( —Preceding unsigned comment added by 65.185.10.34 (talk) 21:29, 16 October 2007 (UTC)

[edit] 2^255 cluster size, that's great :)

it has to be 2^25 i think, because 2^25=32MB

I agree that it does look a little weird, but look here [1] and you'll see that they too say that theoretically the FAT64 file system supports cluster sizes of up to 2^255. I guess they simply felt that oversizing one particular field in a header in order to absolutely guarantee future-proofness is a minor waste of space (32 bytes is really nothing). I would guess that the cluster size field is simply 256 bits long. Unsound (talk) 04:57, 7 June 2008 (UTC)

[edit] Windows Server 2008

I added Win2008 to the initial description but couldn't find an external source...I know it supports it because I just formatted my flash drive with it :-) I suppose I can't use a screenshot of the format screen as a citation... —Preceding unsigned comment added by 209.143.2.97 (talk) 14:29, 16 May 2008 (UTC)

I can verify that. File system driver exists in Windows Server 2008 and there is support in the "format" utility. So it's fully usable. I added it to the info box. Unsound (talk) 04:47, 7 June 2008 (UTC)

[edit] Merge with File Allocation Table?

All other FAT file systems are listed under the File allocation table article, and I don't think exFAT/FAT64 should be any different. Unsound (talk) 04:43, 7 June 2008 (UTC)
