The confusion is because you didn't clearly explain what you are looking for. "Multifile".. is more than a little ambiguous without a context or elaboration. Or you can try blaming it on the emoticon. Emoticons are always bad.
Anyway, you are apparently looking for Odin formatted components e.g. bootloader, modem, etc, rather than the complete tar firmware image. Most firmware repositories have the complete firmware which contains all of the components. To obtain the separate items, you really need to pull them from the full firmware image and repackage (tar) them. Samsung does package the components separately, but AFAIK only for internal use. I'm not aware of Samsung distributing or providing end user links to the components.
If you search the forum, you will sometimes find that someone has done the work for you. e.g. if you had a 900T phone, this thread would be useful to you:
[Stock Collection] Kernels, Modems, Firmware, Stock Tars[Current: NG3]
As to PIT files, note that a PIT (partition information) is unique to a model, ROM size and carrier. So if you have a 900F phone, 16 GB, carrier x.. that PIT file is different than a 900F /32 GB /carrier x or 900F /16 GB /carrier y PIT file.
Unless you are changing carriers or have partition corruption, you can simply extract a copy of the PIT file from your own phone. Have a look at this thread.
The matter is i`m looking for FACTORY FW, but not for HOME.
In a firmware there is cache.img or cache.img.ext4 in which there is / recovery/command where key difference of firmwares of HOME from FACTORY is shown.
command for factory:
command for a normal firmware:
That as for division of an one-file firmware into components it is clear and I did it many times.
At a forum I recently, but Samsung am engaged in devices long ago.
