Jeff,
Here's my best guess as to what is happening...
When you chose "Save As", somehow the folder you refer to (td_003.dir) is likely the "filename" which excel saved the file under.
Excel has a "default" setting of only showing files which have the normal Excel "extention" - which is "xls". Therefore, when you went to open the file, Excel is NOT showing the file - because it is ONLY looking for the "xls" type of files.
To enable Excel (and yourself) to "find" the file, you need to: 1) Use the Open function (Control O), and 2) In the bottom-left corner of the Open window, click on "Files of Type" and change this to "All Files". Then Excel will display ALL files in the folder, and your "td_003.dir file should be there.
Being a valid Excel file (hopefully, just named incorrectly with the wrong extention), you should be able to open it. Once you open it, be SURE to save it with the PROPER extention - i.e. "xls". So, use "File Save As", and change the filename to "td_003.xls".
Hope this helps. Please advise.
