Finally got it the problem was in name of the extracted file
Any one that has same problem can do this
After extracting learn-glsl-shaders-from-scratch.7z_1 you will get file with learn-glsl-shaders-from-scratch.7z_1 name
Then change that file name to learn-glsl-shaders-from-scratch.7z.001
and then you can extract the files correctly
And yeah finally thanks NihilisticJedi for sharing this
from what i seen this is older version of the course
if you find latest one pls share👍
