No, because even if you translate the Base64 data back to binary (even partially) not all files contain any "markers" that identify it as a particular type of data - that's the job of the filename extension, and though some file formats do include a header which identifies them to a reader of that file type as "correct info" most do not.

Look at the originating software to see what it does with the file extension - if it prefixes it into the Base64 string you are laughing. If it doesn't ... you probably have no way to identify file type from content reliably.
