What do you call the operation of copying files from NTFS ... to FAT32 ... then?

Copying. Or, if you look at the filesystem driver level, reading from NTFS and writing to VFAT.

Regarding FAT names - see also File Allocation Table:

FAT-12, FAT-16, FAT-32 specify the size of a FAT entry, in bits, and thus indirectly also the maximum filesystem size.

VFAT extends the FAT by adding long filenames (everything beyond "8.3", including mixed case, spaces, and more allowed characters).

Linux has several closely related filesystem drivers, "fat" is a common part of the "msdos", "umsdos", and "vfat" drivers. The "msdos" driver is for plain old DOS disks, "8.3" names, no extras. "umsdos" (no longer enabled by default) implements Unix file attributes and long filenames on top of a plain, DOS-compatible FAT filesystem, by storing extra data in a special file per directory. "vfat" implements FAT with long filenames à la Microsoft.

ExFAT (as found on SDXC-Cards) and FATX (Xbox) do use a FAT, but with very incompatible structures due to the very different feature set.
