Answer:

Rename it with the proper extension. BAK files are created by some programs as back up versions of databases or documents in case something happens to the current version. If you sort by name in a directory, you'll find the .bak file right next to a file with the same name, only with a .doc or .ftm or some other extension.

Give the file a 1 at the end of the name (Don't want to over write the current file) and change the extension and you'll be able to see what it is.
