I have tried upload 8 files fastq ( total size of 8 files 1,4 Gb).
But I have started this morning and still It not finish.
It's possible that there are some problem?
I have tried by the browser. Ok, I'm going to test by ftp.
Are you uploading the data through your browser or using FTP client? If the answer is browser please try FTP: https://wiki.galaxyproject.org/FTPUpload
