MSKB article:

Hi, I'm having trouble exporting a budget spreadsheet from Excel (on desktop)
to my pocket PC (pocket excel). Tried copying and pasting but an error
message reads: Cannot convert file. The process cannot access the file
because it is being used by another process. I have no idea what that means.
Any help would be greatly appreciated!!

Thanks,
Selena
