Relate to space reclaim after files delete.

Question for expert out there please.

Let said my cluster has 20GB space and I have a folder usage 10GB and with snapshot protection technology the folder end up used let said close to 20GB.  I decide to delete the 10GB folder to free up some space but keep the snapshot remain until retention period expired. Will the cluster reclaim the 10 GB space for me to used that I would think??

Thanks so much!
