Hi Osmond,
First you need to determine precisely where you uploaded the zip file to. For example, I'm guessing you uploading it to wwwroot. So in the Kudu command window the path would be C:\home\site\wwwroot<yourfile>.zip
Once you know the exact file path your file is saved in you can use the unzip command in Kudu command prompt. Before unzipping the files you want to plan out where you want them. c:\home\site\wwwroot is the root folder of your site, so this is where you would want the entry point (index.html or similar) to be saved.
For example, you could first switch to the directory where your zip file is saved (substitute the path yours is saved in) using below command:
cd c:\home\site\wwwroot
Next unzip the files using below command:
unzip <yourzipfilename>
If you are unsure how to use the unzip command, you can type unzip -hh
to give you a list of command line switches and help text.
Other options you may consider are unzipping the files on your local PC and uploading them using FTP or Kudu, deploying via GitHub/Bitbucket/etc., deploying via Visual Studio or VS Code.
