Question: How large are the files that can be sent through the cloud-based file transfer service created by the founder of WeMarket?

Context paragraphs:
File transfer: File transfer is the transmission of a computer file through a communication channel from one computer system to another.  Typically, file transfer is mediated by a communications protocol.  In the history of computing, a large number of file transfer protocols have been designed for different contexts.

LeechModem: LeechModem was a BBS file transfer protocol client.  LeechModem was compatible with protocols like XMODEM (and YMODEM), but it would mischievously NAK the last packet and then abort the file transfer.  The user had successfully downloaded the file, but the BBS would mistakenly not count the aborted file transfer against the user's download quota.  The user would need to know and input the filesize before the transfer so the client would know when to abort.

WeTransfer: WeTransfer is a cloud-based computer file transfer service.  The company was founded in Amsterdam (the Netherlands) by Bas Beerens and Nalden.  The core service is free, with more features available for premium accounts.  Free users can send files up to 2GB; WeTransfer ‘Plus’ supports sending files up to 20GB and offers features like password protection, channel customization and 100 GB storage.

MagicVortex: MagicVortex is an Internet-based file transfer service.  It is a hosted solution intended to simulate a person-to-person transmission of any type of file up to 2 GB in size, depending on the subscription level.  Files can be sent either by an Internet browser or by a downloadable application for Microsoft Windows.  Notifications are sent via email, but all data transmission is protected using SSL encryption.

ZumoDrive: ZumoDrive is a defunct cloud-based file hosting service operated by Zecter, Inc.  On December 22, 2010, Zecter announced its acquisition by Motorola Mobility.  The service enabled users to store and sync files online, and also between computers using their HybridCloud storage solution; the latter functionality stopped working in approximately September 2011, while the former was undergoing formal takedown on May 1, 2012.  ZumoDrive had a cross-platform client (Windows, macOS, Linux, iOS, Android, and Palm webOS) that enabled users to copy any file or folder into the ZumoDrive virtual disk that was then synced to the web and the users' other computers and hand-held devices.  Files in the ZumoDrive virtual disk could be shared with other ZumoDrive users or accessed from the web.  Users could also upload files manually through a web browser interface.  A free ZumoDrive account offered 2 GB of storage, and users could upgrade to paid plans ranging from 10 GB to 500 GB for a monthly subscription fee.  The ZumoDrive service was integrated into Yahoo! Mail, allowing users to send or receive any file on their ZumoDrive (the integration with Yahoo! Mail has been stopped as of June 1, 2012), and powers HP's recent CloudDrive technology, bundled on all new HP Mini netbooks.

WeMarket: WeMarket is a global personal B2B marketplace for large and small suppliers and buyers.  Founded by the creator of WeTransfer, it allows global companies to buy and sell products easily in any industry.

HS/Link: HS/Link is a file transfer protocol developed by Samuel H. Smith in 1991-1992.  HS/Link is a high speed, full streaming, bidirectional, batch file transfer protocol with advanced Full-Streaming-Error-Correction.  Each side of the link is allowed to provide a list of files to be sent.  Files will be sent in both directions until both sides of the link are satisfied.

EFTP: EFTP (various expansions of this have been given, including Easy File Transfer Protocol, Ether File Transfer Protocol, and Experimental File Transfer Protocol) was a very simple file transfer protocol developed as part of the PUP protocol suite at Xerox PARC in the late 1970s.  It was part of the inspiration for the Trivial File Transfer Protocol (TFTP) in the TCP/IP suite.

RapidShare: RapidShare was an online file hosting service that opened in 2002.  In 2009, it was among the Internet's 20 most visited websites and claimed to have 10 petabytes of files uploaded by users with the ability to handle up to three million users simultaneously.  Following the takedown of similar service Megaupload in 2012, RapidShare changed its business model to deter the use of its services for distribution of files to large numbers of anonymous users and to focus on personal subscription-only cloud-based file storage.  Its popularity fell sharply as a result and, by the end of March 2015, RapidShare ceased to operate.

SSH File Transfer Protocol: In computing, the SSH File Transfer Protocol (also Secure File Transfer Protocol, or SFTP) is a network protocol that provides file access, file transfer, and file management over any reliable data stream.  It was designed by the Internet Engineering Task Force (IETF) as an extension of the Secure Shell protocol (SSH) version 2.0 to provide secure file transfer capabilities.  The IETF Internet Draft states that, even though this protocol is described in the context of the SSH-2 protocol, it could be used in a number of different applications, such as secure file transfer over Transport Layer Security (TLS) and transfer of management information in VPN applications.
