If you have multiple files to send to Nomalab, Nomalab can provide you an AWS S3 Bucket, where you will be able to drop your files via software like Cyberduck.
This way, you will have a more consistent connexion than using your web browser upload.
WARNING : It is mandatory to use a clear naming for your files, to help Nomalab to retrieve them easily and upload them on your organisation stock in Nomalab.
1/ First step is you ask firstname.lastname@example.org for a AWS S3 Bucket creation.
2/ When bucket has been created, you can download and install Cyberduck for Mac Software
3/ When the software is launched and ready, click on "+" button at the bottom left of the window

B/ Enter your Access key in this area (given by Nomalab)
C/ Enter the Secret Key given by Nomalab
D/ Enter the bucket name given by Nomalab
When everything is filled, go back to the previous menu and double click on the disk you just created
