Using Mac OS, copied 54GB iphoto .photoibrary from external HD to brand new Extreme Portable SSD 500GB and final result is over 300GB. 54GB iphoto photolibrary is same size (consistently 54GB) on multiple other external harddrives. Only Scandisk balloons file.
“Get Info” on folder is endless cycle of “calculating size” but DaisyDisk quickly reveals ultimate size.
Any suggestions for how to retain original photolibrary size?
