文件类型2：Backup File

文件说明：

Backup of another document, often created automatically by various programs or the operating system; for example, Windows may create BAK files for the System.ini and Win.ini files.

NOTE:

The file extension should be changed back to the original extension in order for the file to open correctly; this is often done by simply removing the .bak part of the filename.

For example, mydocument1.doc.bak should be renamed to mydocument1.doc before being opened.
