Microsoft+Excel+2007+Bug+&+Solution

Q: My Microsoft Excel in Office 2007 no longer supports a specific format I am trying to use, why is this?  A :  Historically Excel has supported many different data formats. We have determined that a number of these older formats are seldom, if ever used. We are removing support for some file types to allow us to devote more of our efforts towards the file formats that are being used. Theses formats are being deprecated in 2 ways. For the set of file formats with the lowest usage, we will be discontinuing support for opening and saving of these formats. For the second set that has some minimal usage, we will support loading the files in Excel 2007 to allow you to save them in a newer format. The following formats cannot be opened or saved in Excel 2007 :
 * WK1 (1-2-3)
 * WK4 (1-2-3)
 * WJ3 (1-2-3 Japanese) (.wj3)
 * WKS (1-2-3)
 * WK3,(1-2-3)
 * WK1,FMT(1-2-3)
