I deleted all my histories and data in galaxy, refreshed for recalculating space, I use 25% and I have this message:
You are using 64.5 GB of disk space in this Galaxy instance. Your disk quota is: 250.0 GB. Is your usage more than expected? See the documentation for tips on how to find all of the data in your account.
How can i get more space on the disk?
Thanks for your answer.
