EDIT 2020-06-13: Below link isn't available anymore. In post #5 is a link to the converted syx ->> FM8 presets. billions of Yamaha DX-7 files in .syx formats you will find here: http://korgpatches.com/patches/kronos/dx7_200k_collection enjoy
We'll....not billions...200,000 to be precise. Thanks for this link. I'll add my usual advice for "boosting" old DX7 patches to make them sound better in FM8: 1) Go to the <Easy> page and lift the Stereo Width - works magic! 2) If possible, increase the output volume. Most old patches are too soft. 3) Tweak velocity sensitivity on some operators - makes the patches more "live" 4) Add reverb or delay etc - season to taste. I also often reduce the detune parameter as many patches sound far "tighter" when this is decreased. A slow chorus works a lot better on a pad patch than a hideous detune which renders the sound irritating and incompatible with other instruments. One more thing to note: When importing banks to FM8, look out for any patches which have "restricted" characters * (star) . (period) / (slash) If the patches contain any of these, they will be left out when importing. Any older users who have FM7 will be able to re-name these patches and re-save before importing into FM8. New FM8 users don't have any options that I'm aware of. Hope this is helpful....

It could convert from the suffix mid, dx??, tx?? to SYX. the 4 kb files also. So all formats can't read by FM7 are in this collection. All banks in one file.
