Unknown ZZZ folders in my system drive

There are three Unknown folders in my system drive, I dont know how the folders are created in my system drive.

These Unknown folders are named as
3590F75ABA9E485486C100C1A9D4FF06Z.Z.Z.ZZZ…Z…ZZ
3590F75ABA9E485486C100C1A9D4FF06Z.ZZ…ZZZ.ZZ…Z
3590F75ABA9E485486C100C1A9D4FF06ZZZZZ…Z.ZZZ

folder 1 = Z folder
folder 2 = ZZ folder
folder 3 = ZZZ folder
All the files in these three folders are .Z, .ZZ, .ZZZ files.

View the images of the unknown folders found in the system drive attached with the post.

What to do about these three folders?
