What ho all self isolators,

With time on my hands, I am attempting to regain space on my C: partition, which is sufficiently large at 100Gb with around 60 Gb used.

However, I have found these in C: and have no idea what they are and if I need them? I think not as they don't exist in some older images that I have and I don't recall seeing them in the past.

Attachment 15319

Can I deleted them?

Thanks and toodle pip
