By default Microsoft Office applications keep track of the last 4 files you have opened. When you go to the File menu you will notice a list of these last 4 documents that you can click on for a quick way to reopen the file.
The number of recently used files can be changed if you want to Office to display more or less than the default 4 files.
To do this go to Tools then Options and then select the General tab. There you will see a section that says Recently used files list. From here you can change the number to anything from 0 to 9.
