I thought I'd do a cleaning to make sure my gw.dat file was the right size. I had done a -image before and it was a little under 5 GB. I deleted gw.dat, and ran a new -image. I ended up with 7.12 GB instead. Clearly not all those files are still necessary, because it told me I had all the current files decompressed back when the .dat was 5 GB. How do I get rid of whatever extra stuff is now there? The original idea had been to remove any extra old files.
