Dear Indeepa,

Yes, You can not import database zip file on odoosh, Because of When we make zip from our system , & export. It's create a folder. 

Example: Database.zip

• Extract structure like: 
• Folder: Database
• File:  Database/dump sql
• Folder: Database/filestore/<all files>

But when odoo wll import they preferred extract directly files  & try to find. 

In your case 2 Extension available, Rayin_Group_New_2025-01-31_04-02-39.zip.ZIP Please make correct Zip file.  

Thanks

Hi, I have the similar problem.

(please check that you have transferred or created the zipfile in the

appropriate BINARY mode and that you have compiled UnZip properly)
you then found a solution, if that is the case. how did you? and what is the source of the problem?
