Microsoft Office 2010 Upload Center opens the wrong file on a SharePoint Server

You use an Office application on your computer to open a document on a SharePoint Server. For example, you try to co-author a document in Word, or to access it from Microsoft SharePoint Workspace 2010. Instead of opening the document that you wanted to open, a prior document is opened.

This issue occurs when the following conditions are true:

• The document that was opened was previously opened and then closed by using Microsoft Office 2010 Upload Center. This behavior occurs before you try to open the second document.
• The file names of the two documents differ only by a few characters, and at least one of these characters is not included in the Basic Latin character set. For example, the two file names each contain one of the following characters:
  • the Latin uppercase letter "I" with a dot above it: "İ"
  • the Latin lowercase letter "i"

Office 2010 Upload Center stores copies of files that you have opened from Office Document Cache. When you open an Office document, Office Document Cache converts the file name of the document into lowercase characters and then opens the cached version of the file.

In the example that is mentioned in the "Symptoms" section, Office Document Cache converts the "İ" character to the "i" character. If two documents have names that differ only by this character, the wrong document may be opened. This behavior occurs when one document was previously opened and then closed and when the document has a similar name to the document that you want to open. Additionally, this behavior occurs when the first document is still in Office Document Cache.

This issue occurs because certain characters in file names are converted to lowercase characters incorrectly.

To work around this issue, use one of the following methods.

Method 1

Open documents directly from the SharePoint library by using the Library tools. Do not use Office 2010 Upload Center.

Method 2

Change Office Document Cache settings. Clear Office Document Cache and then prevent Office Document Cache from retaining closed documents.

To clear Office Document Cache, follow these steps:

1. Click Start, point to All Programs, and then point to Microsoft Office.
2. Point to Microsoft Office 2010 Tools, and then click Microsoft Office 2010 Upload Center.
3. On the Settings menu, click Delete cached files.
4. Click Delete cached information to confirm the deletion of the files.

To prevent Office Document Cache from retaining closed documents, follow these steps:

1. Click Start, point to All Programs, and then point to Microsoft Office.
2. Point to Microsoft Office 2010 Tools, and then click Microsoft Office 2010 Upload Center.
3. On the Settings menu, click Delete files from the Office Document Cache when they are closed.

After you clear Office Document Cache, wait until the last saved document is uploaded to the SharePoint library before you open the document that you want.

Method 3

Rename the affected files so that the file names are significantly different. If the files are part of a series, add a number string to the file name to help differentiate between the files.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
