It is my first time working with Galaxy. I have uploaded around 51 GB on Galaxy. But the storage shows 209.12 GB as used space it says that %83 of my storage is used. I still have another 54 GB data that I would like to upload. Can any body help me why is the difference between the amount of data that I have uploaded and what is shown as used space and how can I fix this problem to upload the rest of my data.
