Can I delete these 2 folders from my content folder???

These are the 2 folders that are inside my content folder… I am trying to keep things tidy in here so Id like to keep the size of the overall project down… I am also using Github to share the project/repository with colleagues, so I am pretty sure these folders are relevant to Github…

But… my question is CAN these 2 folders be deleted from the content folder in the project or are they vital?? They are a few Gigs in size so if I can have that space back Id like it…

Im just hoping someone has gone through this already and found an answer they could share… I appreciate any help!

Thanks

One quick way is to simply moved those folders outside of your project, and see if anything breaks… for the record, I never found those folders. Maybe because I am still using UE4…
