Have you tried double-clicking the file icon while in Explorer, or
using File | Open from within Excel? Not sure what you mean by "I open

My folder is where it should be and my file names (12) are in the folder.
However, 11 of my 12 worksheet files that are listed in the folder present
the following message: "If you are trying to open the file from your list of
most recent used files on the File Menu, make sure that the file has not been
renamed, moved or deleted" I open my worksheet using the folder not the most

help me, I have Excel 2003
