Tried removing the files instead of the folder and got a specific error that it was used by NVIDIA share…
Didn’t expect that…
I do use Geforce Experience and Shadowplay to capture videos sometimes but I didn’t have desktop capture enabled.
I went into the settings for Geforce Experience and disabled the in game overlay and then I could delete the files. 
Thanks for the tip about the tools, I tried using this tool but turns out explorer could do it for individual files.
I checked the global path and the picard folder was there… maybe i tried to automate something at some point.
