Hi i cannot open course files it says corrupted
Hi YYiit ,
You're not alone!
The Download files are a so-called 'split archive'.
You need to download all into one folder, then use 7Zip to Unzip the xxx.zip.001. That's all.
Now, it sounds simple, but a lot can go wrong; (most common!) not just Unzipping the .zip.001.
Having not all downloaded into the same folder (or directory, or whatever you call it).
Not using 7Zip (might still work, but is not guaranteed), for instance when not using Windows.
And many more ways to 'mess this up'.... (there are many ways to not get 8 as a result after adding 3 and 5...)
Did you already look at FAQ 5 here:
