How can I read/write bytes to SD card slot of MC60A?

Question

I am working on a clickBoard with MC60 A GSM module from MikroEletronika company.

This clickBoard has two slots: (1) one for SIM card and another (2) for micro SD cards. I have read all the available documentation: AT commands user guide manual (Quectel documentation) and some code examples (Libstock) and i still cannot find any information about how can I communicate with SD card slot.

The only thing I've found about this topic was on quectel hardware guide:

The following are the main features of SD card interface: - Only supports 1bit serial mode; Not support the SPI mode for SD memory card - No support multiple SD memory cards - No support hot plug; The data rate up to 48MHz in serial mode - Support for memory cards with maximum capacity up to 32GB;

From this I assume it is a serial communication. So, with the info I know, the two questions I have are:

Can I write/read bytes with the usage of AT commands? If yes, which AT commands?
It is necessary any specific format for micro SD card (FAT, exFAT, FAT32 or NFTS)?

You will most likely have to pursue this directly with the manufacturer. — Chris Stratton, Nov 12 '18 at 18:33
I already did it. I am just waiting for an answer. Soon as i know how to solve the problem, I'll post here. — Ricardo Goncalves, Nov 13 '18 at 10:29
Do some research before comment. If you know what a MC60 is, and if you read my question, you will notice that MC60 has a SD slot card which can be accessed by AT Commands. — Ricardo Goncalves, Nov 20 '18 at 12:14

I sent an e-mail to quectel manufacturer and they sent me a specific document for FILE AT commands. Here. For some reason, neither MikroEletronica or quectel have this file available on MC60 datasheets.
