When you try to save a file in a Microsoft Office program on a Windows Vista-based computer, the save operation may fail. Additionally, a new 0-byte destination file may be generated.

This issue may occur if the following conditions are true:

• The client-side caching (CSC) feature is enabled.
• A program is monitoring the files or folders on the computer.

In Windows Vista, you use a program’s Save As dialog box to save a file by using the name of another file. You select the file name from the history list in the File name box. However, the changes are not saved by using this file name. Instead, the original file is overwritten.

For example, you have two files that are named notepad1 and notepad2. You modify the notepad1 file, and you want to save the changes to a file that is named notepad2. However, your changes are saved to the notepad1 file. The earlier contents of the notepad1 file are overwritten.

Consider the following scenario. You try to save a Microsoft Office Excel 2007 workbook to a document library on a Microsoft Windows SharePoint Services site. The workbook is not saved as expected. If you make a change in the workbook and then try the save it again, the workbook appears to save as expected. The file name that you specified appears in the title bar of the workbook. However, when you exit Excel, you are not prompted to save the changes to the workbook. In this scenario, the workbook is not saved, and the contents of the workbook are lost.

In Windows Vista, when you try to save a file to a hard disk or to a flash device, you may receive one of the following error messages:
Message 1

X:\Folder\FileName You don’t have permission to save in this location. Contact the administrator to obtain permission. Would you like to save in the Documents folder instead?

Message 2

Access to X:\Folder\FileName was denied.
