552 Disk full - please upload later (HELP!)

[j.munhao71]

Along with some other users, I am also getting a "552 Disk full - please upload later" error when I try to upload files via ftp.

I can upload files using the cPanel file manager, but this is a slow, tedious and disorganised process and would prefer the simplicity of my FTP client while I'm working on my site.

I am using filezilla.

Thanks!​
