You need to set the options for the XLS (or other) back to the default. From
window Explorer in windows XP.

Tools - Options - File Types - XLS ( or other) - Advance

Select OPEN, then press Set Default.

When I try to open Excel files from within Windows Explorer a pop up window
tells me "Windows cannot find the file...make sure you typed the name
correctly."

The same file opens OK if opened from Excel, just not through Explorer.

Could anyone tell me what the problem is and what I need to do to solve it.

Any help would be appreciated.
