If you are afraid of conflicts or other possible problems, see:
How safe is MyDefrag? It remains as safe as it is now, until Microsoft changes the Windows Defragmentation API so that it will become incompatible. It has also been tested by the community, including me, on windows 8 and it has been confirmed fully functioning.
As what it comes to the support of
free product, the developer's latest answer is from 21th of this August. He hasn't abandoned the forums, and there are still active forum members helping each other, even though the forums are under spam bots. It is very sad that there hasn't been any updates or new features, nor confirmation if he will continue developing it further, but nothing stops from using the fully functioning program. It is not food that gets bad after a certain date!
I simply haven't found
any alternatives to MyDefrag. It is that good and unique disk defragmenter. I once used a commercial one called Ultimate Defrag. It was close to MyDefrag but its features were very restricted, and it had many problems and bugs and no support at all. It had new update just lately, it was very easy to know this after the ten email update offers. The new version only came with some minor GUI changes plus renamed functions, and with the same bugs. It was very unpleasant experience with a commercial product for me.
If you are interested comparing the defragmenters, look this very well detailed test:
The Big XP Defragmenter Test I like the conclusion of it, even the standard windows defragmenter functions quite well and in some situations is enough to be used.
