 +===== Quota =====
 +
 +The shared storage itself does not have a quota. However, files stored in a shared space are counted against the personal quota of their owners.
 +
 +**Example:** If Alice and Bob both have access to the shared directory ''/shared/project1'', and Alice stores 500 GB while Bob stores 200 GB, then 500 GB will be deducted from Alice's quota and 200 GB from Bob's quota. If you need more space, you can request that we upgrade your quota, we'll do so if we have enough capacity (hint: we have enough space on Bamboo and Yggdrasil, not on Baobab)
