This problem started only one week ago.
Hello @guptabio , welcome to the Bitdefender Community!
Can you be more specific?

I guess the OP has the same issue with file extensions as described in this post:
Regards.
I clicked on the View button in File Explore, took the cursor over Show and unchecked File name extensions. Nothing changed. I clicked on the three dots near View, clicked on Options, then on View and checked Hide extensions for known file types. Then I clicked on Apply followed by OK. Nothing changed.
Someone suggested that I should uninstall and re-install Bitdefender Internet Security, but I haven’t done that.
File name extensions have become visible only 7-8 days ago.
I'm having the same problem and just submitted a ticket.
Thankfully I am using a 30 day trial version because from what I have read this has been a known problem for years and this is a deal breaker for me as I alter and create hundreds of files daily and having the extensions visible slows me down, thus costing me money.
If you are unable to hide file name extensions via file explorer, check the below stated link and try via command line or by making a change in the registry.

My problem is solved. In Settings, I switched on Developer Mode and then changed File Explorer settings. Then, I switched off the Developer Mode. File name extensions are hidden now.
