2013 File Extension

What is the .2013 file type?

Although most definitely a trailing part of the filename, the string of characters ".2013" may still appear or be an actual filename extension. As an extension, the ".2013" string does not signify any regular file type or file format. Instead, it usually bears reference to the year 2013.

It becomes an extension when the original extension is missing as the result of incorrectly renaming, saving or manipulating movie, document or other files with trailing dot-separated date or year stamps. For instance, a file with the name "annual_report.2013.xlsx" can easily become (or look like) "annual_report.2013".

A file with the actual .2013 extension can be of any format, depending on its original file type. One could attempt viewing the contents of the file with a hexadecimal viewer/editor to look for clues on the file format. Once the correct file type is known or guessed, a proper extension should be manually added.

Also, .2013 can look like an extension on an MS Windows machine with the "Hide extensions..." option turned on (default), in which case the said option should be turned off and the actual file type checked.
