you have to remove all the junk that bunkr adds to the filenames
so for the Skyler Nicole video for example
rename the first part to
UnlimitedAnalScene04_s04_SkylerNicole_1080p_h264.7z.001
and the second part to
UnlimitedAnalScene04_s04_SkylerNicole_1080p_h264.7z.002
(actually the part before the .7z doesnt matter as long as it's the same so it can be whatever.7z.001, whatever.7z.002 etc)
then you can extract the files with
7zip. as long as all parts of the video are in the same folder and properly renamed you can open the first part with 7zip and the video will be inside, you can extract it where you want and then delete the .7z files
