I recently converted a 6 GB of FMP7 file to FMP12 using FMPro 17. The FMP12 file has the same 6 GB file size. I then did a "Save A Compacted Copy". The new file size has reduced to 4.5 GB. I am just curious why doesn't FileMaker does the compacting during the conversion from FMP7 to FMP12 ? To me, this is the most logical thing to do.
