There is only one of my Excel 2003 files that almost disappears when I copy it over into my Windows 7 laptop and try to read it with either explorer or search for it, although it asks me to replace it everytime. It appears as if it doesn't exist. However when I open Excel 2010 and list only the .xls files, it finds it and I can read it. I have several other Excel 2003 files that are fine and since I usually open files by clicking on them in explorer, this one is particularly annoying, since I can't find it to click on it to open it. When I do open it in Excel 2010 it works normally and fine.
Can anyone tell me why only this file disappears from explorer and the search function only?
