I am Downloading BIM objects from this site , but the file refuse to Extract

Thank you Liz , i will try it

Hi Osama,
The issue has been fixed, so if you download the files again, they should be extractable.

Hi Osama,
We are working a solution now. I will let you know when you can try again. Do let me know if you need any files urgently, in which case I can try to email those through while the issue is being fixed.
