What are the maximum volume sizes and maximum file sizes for the various Windows file systems?

A. Windows 2000 and later support FAT, FAT32, and NTFS file systems. (The next version of Windows, code-named Longhorn, will support a new file system known as WinFS). The table below lists the maximum volume sizes and maximum file sizes for FAT, FAT32, and NTFS.

  FAT FAT32 NTFS
Operating systems All versions of Windows and DOS Windows .NET Server 2003, Windows XP, Windows 2000, Windows 98, Windows 95 OEM Service Release (OSR) 2 Windows .NET Server 2003, Windows XP, and Windows 2000 support NTFS 4 and 5 (previous version of Windows NT support NTFS 4 only)
Maximum volume size 4GB 2TB (although Windows XP lets you format only up to 32GB but can read larger volumes) You can use 64KB clusters to achieve a 256TB volume (any volumes larger than 2TB must be dynamic, not basic)
Minimum volume size Floppy disk 512MB 10MB (although some tools let you format a floppy drive as NTFS, see Sysinternals.com)
Maximum file size 4GB 4GB Size of volume
Maximum files per volume 512 files or folders per folder * 65,534 files or folders per folder * 4,294,967,295

* If you use long filenames, you will reduce the number of files per folder.

actually, you can format FAT32 to more than 32GB, but internal limitations of SCANDISK limit you to 32GB. So you're not safe on ME/98 boxes. see http://www.dewassoc.com/kbase/hard_drives/hard_drive_size_barriers.htm for HD/OS size barriers in depth. the individual drives are limited to 2.2TB due to 32-bit addressing limitations, but the volume size apparently can be larger. Now that we have 1TB drives, this limit will soon be a problem and we will need new OSs or an OS patch & new filesystems to run the bigger disks.

Has anyone read about additional ntfs volumes

I recall reading somewhere that the 256TB size is applicable when combining volumes, like with spanned, mirrored or striped volumes

I dual boot ME and XP.
For compatibility, when I initially installed XP from ME I formated a SATA 160Gb drive from the ME command line to a single 150Gb FAT32 partition and then installed XP on this partition.
Works fine, very few disk related problems.

does anybody know what will change in WinFS?

For the question on mounting points, it's possible to mount a unmounted or mounted volume in an empty NTFS directory with graphical tools.
You can use command line tools as described in http://support.microsoft.com/kb/205524/en-us#kb1 .

Is there any way that it is possible to store a file larger than 4GB on a fat32 disk?
The file I'm trying to store is 4,5 GB and since I have a laptop I cannot build in a ntfs disk which makes this problem rather annyoing...

Any help would be greatly appreciated!

I have a problem with file limitations. I have a surveillance program that connects to 8 IP cameras. The cameras are set with motion detection, they take pictures throughout the day. The problem is, all of the cams' pics are stored on one WinXP box, and the maximum number of files I can get in a folder is 16,384. So if I forget to move the pics off one day, the cams' pics are not captured once the folders reach the 16,384 maximum. The drive is NTFS, and the file name are formatted; cam1_03-15-2005_11-30-30-am.jpg, and no, I cannot change the filenames, I need these for archiving purposes.

Thanks!

with windows 2000 or 20003 is still drive letter limitation (A-Z) and if so is there other mounting points if you ran out of drive letters?
