Like AOMEI etc. DiskGenius offers both free & paid versions -- you can see what's included here:

IMHO the GUI isn't as nice as AOMEI's or Paragon's, or really any of the other partitioning apps I've tried, but this one stands out for having a portable version that actually is portable, with no drivers installed [you will get new registry entries from Windows basic housekeeping, so it will be possible for someone to tell that you ran the app].
