After saving a file using Excel 2010 in the My Documents folder, it cannot be found using the open button in Excel 2010

Question

When certain files are saved using Excel 2010 to the My Documents folder, they cannot be found by using the Open button within Excel 2010.  But the file is always found using My Computer and following the path to My Documents.  What is
even odder is that if I do a "Save As" within Excel and rename the file to the same name but with a "!" at the beginning of the name, it will then show up in the Excel Open window.  There doesn't seem to be a distinct pattern as to
when the file can or cannot be displayed by the Excel Open button.
I am using Windows 7 64bit along with Office 2010 64bit.  Windows has current service packs and updates.  There are perhaps 200 - 400 Excel files in the My documents folder. Some of them are .XLS and some are .XLSX.

Hi,
Do you mean that you can't find the Excel file when you click Excel->Open->My Documents folder? 
Do you use the other folder path to test?
Dose the issue occur in other Office suits (Word, Power Point)?
Do you get some error message, like "Windows cannot find 'FilePath\FileName', Make sure you typed the name correctly, and then try again."?
Please try the following methods:
Method1:
1. Go to the registry. Click START, and in the RUN command line type REGEDIT and hit ENTER or click OK.
2. Navigate to the following key: HKEY_CLASSES_ROOT\Excel.Sheet.8\Shell\Open\Command
3. Double click on the (Default) instance over to the right. Right now this probably says something like:
C:\Program Files\Microsoft Office\Office14\EXCEL.EXE /dde
Change this value to:
C:\Program Files\Microsoft Office\Office14\EXCEL.EXE /e "%1"
4. Navigate to the following key: HKEY_CLASSES_ROOT\Excel.Sheet.12\Shell\Open\Command
Again, double click the (Default) entry to the right and change
C:\Program Files\Microsoft Office\Office14\EXCEL.EXE /dde
to
C:\Program Files\Microsoft Office\Office14\EXCEL.EXE /e "%1"
Note : Please backup the registry key before you modify.
Method2:
Click the File tab, and then click Options.
Click Advanced, scroll down to the General
section, and then clear the Ignore other applications that use Dynamic Data Exchange (DDE) check box in the
General area.
Thanks
