Upload add by a file

[Power Hoi]

I want to upload app by the file where is placed in my computer.

But as you can check upside picture, only URL way is there.

How can I upload Add-on file(*.jar) on the confluence?

Your screenshots are from two different pieces of software.

Confluence Cloud and Confluence Server do not have the same app framework.  Server apps cannot be installed on Cloud, and Cloud apps cannot be installed on Server. 

Your first screenshot is from Cloud, your second is from Server.

Assuming your target system is Cloud, as per first screenshot, then what you have to do is forget the upload, identify (or write) a Cloud app that provides similar functions to whatever the server app was supposed to do, and install that.

Dear Nic

I really appreciate your answer.

Because of it, I can solve the matter, and I am working it without any problem.

Have a good day!
