13.3. Windows Preview Pane locks files for extended period
THE INFORMATION IN THIS ARTICLE APPLIES TO:
- WAFS, all versions
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:
- 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.
- Click Organize -> Layout.
- Clear Details Pane.
- Clear Preview Pane.
In Office 2010:
- Go to File > Options > Trust center > Trust Center settings.
- Clear Protected View.
- Click OK.
In Office 2010/2013:
- Go to File > Options > Trust center > Trust Center settings > Trusted Locations.
- Place a check next to Allow Trusted Locations on my network as shown below.
- Click OK.
