How to send all files from one org to different org in Salesforce?

Hi @Rajni Gandha

If you're looking for a quick and user-friendly AppExchange solution, I recommend trying the 

Mass File Migrate app. It allows you to seamlessly migrate or transfer files—including Attachments, Classic and Lightning Notes, Documents, Chatter Files, and My Library files from one Salesforce org to another with just a few clicks.

There’s no need to write any code or prepare Excel sheets. The process is streamlined and designed for easy use by admin users.
