OS5: How to remove restriction of 5 GB maximum filesize for remote upload?

@Strontium90 The limitation of 5 GB upload using Web App in My Cloud OS 5 cannot be removed.
Alternate solutions can be FTP Server, WinSCP via SSH. GoodSync Free for WD can also be used, just make sure to install the GoodSync Free for WD Version and not the GoodSync Desktop Version which is not free when used with a My Cloud.
