9.3. Windows Preview Pane locks files for extended period

THE INFORMATION IN THIS ARTICLE APPLIES TO:

SYMPTOM

On a Windows Vista or Windows 7 computer, you may see a "File in use" or "File_name is locked for editing by user_name" message when opening a Microsoft Office document (e.g., Excel or Word file) in a remote shared folder in Windows Explorer that used the Details view and the Preview Pane layout. This is caused by Windows holding a lock on the files for longer than normal, which is behavior associated with the Details view and Preview Pane layout. Per Microsoft Support, the cause of this issue is a sharing violation that happens between the operating system and the Office application over a network resource.

WORKAROUNDS

On desktops accessing the files on a remote shared folder, modify the following settings to disable the Windows functions that cause this behavior:

Windows Explorer:

  1. Click one of the following: Tools > Folder Options > View or Organize >Folder and search options.
    • Clear Show pop-up description for folder and desktop items.
    • Clear Show preview handlers in preview pane.
  2. Click Organize -> Layout.
    • Clear Details Pane.
    • Clear Preview Pane.

In Office 2010:

  1. Go to File > Options > Trust center > Trust Center settings.
  2. Clear Protected View.
  3. Click OK.

In Office 2010/2013:

  1. Go to File > Options > Trust center > Trust Center settings > Trusted Locations.
  2. Place a check next to Allow Trusted Locations on my network as shown below.
  3. Click OK.​​

RESOLUTION

Windows Vista: A HotFix is available from Microsoft Support at http://support.microsoft.com/kb/942146.
