Solution: In computing, ".bak" is a filename extension commonly used to signify a backup copy of a file. When a program is about to overwrite an existing file (for example, when the user saves the document they are working on), the program may first make a copy of the existing file, with .bak appended to the filename.

In a similar manner, a user may also manually make a copy of the file before the change and append .bak to the filename.
