It depends on which version of Windows you are using.

XP partitioning program only allows FAT32 partitions up to 32GB, 2000 will allow higher.

@adambaz,

My answer was based on the Zones in which the asker posed the question. Note that one of those is Windows 2000 Operating System.

The question didn't ask how large a partition you could create with any specific OS ... it asked what the restrictions were for the specific file systems (FAT 32 & NTFS).   Specifically, "... What is the minimum and maximum partition size supported by FAT 32 and NTFS file system " ==>  The answer is as shown in the chart referenced by souseran:

File System       Minimum Partition Size       Maximum Partition Size
    FAT-32                         512MB                                2TB
    NTFS                             20MB                                15EB

Note that support for these sizes does NOT depend on which version of Windows you're using => all OS's that support FAT-32, for example, can read/write to a full 2TB FAT-32 partition.   The restriction noted above regarding XP is simply in the Disk Management plugin, which will not create a FAT-32 partition larger than 32GB.   It will read/write just fine to any valid FAT-32 partition, however, no matter what the size.   If you want to create FAT-32 partitions larger than 32GB it's simple to do --> just use any of the various 3rd party formatting tools, such as http://www.ridgecrop.demon.co.uk/download/fat32format.zip

@garycase,

Thanks for that explanation. It makes a lot more sense to me now. :-)

Objection.

Even in his response ({http:#a20347289}), garycase states, "The answer is as shown in the chart referenced by souseran." That answer is {http:#a20344014}.

I would suggest a split with souseran and my answers --> he referenced the basic chart; I expanded the answer to note the specific restrictions within XP and how to bypass them.
