We have an emergency to deal with right now. We cannot get into I-Link this morning due to low memory. PTC has recommended we free up some space to get things going again. I am sure our IS will add more space soon but we have an immediate need to get things going. Right now ALL versions of every file is saved in commonspace. Can we just purge (after a back-up) all old versions? It seems to me we would not lose any dependencies doing this. Any advice would be appreciated.
