Hmmm... you don´t advertise this but it´s a fact that Free accounts can´t upload files greater than 50MB via FTP...

I don´t know if this limitation also aplies to your file manager because I don´t use it... I prefer FTP for transfering files...

It would be better to advertise this...

From what I see, if your FTP supports resume feature, you can upload files bigger than 50MB. It will be interrupted after you have uploaded 50MB. But you can resume later. I use DriveHQ FileManager. For a free service account, it keeps asking me to upgrade to premium service after uploaded 50MB. While I can click Ok to ignore it, it's quite annoying. So I upgraded later. Overall, I think the software and service are worth to upgrade.
