I have downloaded and installed a local instance of galaxy on the linux server using my user account according to here:

Then I ran the following command:
> sh run.sh
and accessed galaxy through the local firefox browser on the server

Now I am trying to use some NGS files for FASTQ Groomer. Each file is in the server disk already, but very large (~8G each).
I was not able to use the "upload file from your computer" function under the "Get Data" tab (maybe because each file is too large).

What am I supposed to do?

Thank you!
