Is it possible to get a good estimate on how much space a feature class will take once loaded into ArcSDE from how big they are in a FGDB? I have some feature classes in a FGDB, where some are a few GB's.
I'm using Oracle/ ArcSDE 9.2
you can get the same information here - How to get the size of a file geodatabase feature class on disk?
i hope it helps you...
for ArcSDE run the script below in MSSQL Manager Studio. Then save it as csv, open in excel and sort / sum ...
