You posted to the orphaned Acrobat Reader Mobile (Beta), which only gets spam and misplaced posts. Most misplaced posts belong in Acrobat Reader Mobile, but you mention Windows File Explorer, so I'll move your post to the Acrobat Reader forum. Please let us know if I guessed wrong.

Can you show a screenshot of what you are seeing in Window File Explorer?

And can you make sure your file extensions are visible?

File Explorer > View tab > Show/hide group > enable the File name extensions check box

One possibility is that your file associations need to be reset, but it could be something else.
