I'm not aware of any partitioning scheme with a 63 partition limit.

The two major disk partitioning schemes are MBR and GPT.

An MBR disk (the vast majority of disks) can contain a maximum of 4 primary partitions;  but one of those partitions can be an "extended" partition, which can contain as many logical volumes (effectively partitions) as you choose to create.       Using logical volumes within an extended partition, you could have a partition mapped to every letter of the alphabet; and then map additional partitions to folder names (as you suspected).


With GPT disks (which you can only use on systems that support this) you can have an unlimited number of partitions according to the specification;  but Windows implementation of GPT only allows up to 128 partitions.     These are all effectively "primary" partitions, since there's no special "extended" format.

... just noted the zones you selected for this question.    Note that Windows XP does not support GPT formatted disks, so you're restricted to MBR disks with an extended partition to get more than 4 partitions on those systems.     Server 2003 can read GPT disks (but not boot from them) as long as it has at least SP1 applied.    Windows 7 can use GPT disks with no problem;  but can't boot from one unless the system has a UEFI BIOS.

is it possible  you are referring to extended partitions, which can be subdivided into logical partitions?

You can create 3 primary and 1 extended partitions. Inside the extended partitions you can create as many partitions as you have space. As a test I created once 400 partitions. Not with Windows but with third party partitioning tool.
