Is there some WinAPI way to get maximum file size for specific drive?

For example, I know that in FAT32 maximum file size is 4GB. Should I find out that file system on a drive is FAT32 and then use my previous knowledge about FAT32 or there is a way in Windows to get the max file size directly?

What I already do:

I determine file system type using GetVolumeInformation and then use a mapping table that maps file system type to its known maximum file size.

What I want:

I would like to know whether Microsoft has provided a way to get directly the maximum file size in bytes for an arbitrary file system type, even the one that do not exist yet and about which I cannot have knowledge by definition now.

No. Microsoft does not provide an API for that particular piece of information.

Yes.

There is no way provided.

That is what you have to do.
