Good day MILIND, thanks for your question. I am glad to be able to provide assistance to you today. If you are referring to the worlds, you can check and see if you will be able to locate it via from the run command by pressing Windows key + R and then copy and paste this (%LocalAppData%\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds).
Regards,
Paul R.
