Disk Spiking to 100%

So, I've been having this issue for a couple weeks now and I've been trying to fix it ever since. My Disk usage is wanting to spike to 100% only when I'm on FFXIV, and while it shows system at the top—the second I close out the game it returns to normal. If I log into other games, the issue does not exist there. It is only happening with FFXIV.

I'm not sure what to do, as I've uninstalled a few things, deleted a bunch of photos, etc. and I will be attempting a reinstall later tonight and tomorrow to see if that fixes it—I'm just confused as to what's happening? It didn't do this when I installed the game back in I think January? and if it were going to happen I'd assume it would happen then.

Here is an imgur album of the task manager with FFXIV and Guild Wars 2, another game I play, showing the issue is present only when on FFXIV. I couldn't get the images to size down without being fuzzy (probably just because I don't have photoshop reinstalled yet), so I tried an imgur album. It was... semisuccessful, but I've also linked on each photo the full size images.

I'm going to try a complete reinstall through tonight and tomorrow, but if the problem persists I'm unsure of what to do next.

Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

To prevent repeating previously attempted troubleshooting, what have you tried to alleviate the problem? Does this issue happen when Final Fantasy XIV is the only program running? Also, could you provide a system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

Thank you for visiting the Final Fantasy XIV Technical Support Forums.

Hi, have you found a solution to this issue? I'm also having disk usage spike to 100% when FF14 start and then BSOD. Only happened to FF14 and not other games.
