This is cause by Windows Explorer’s thumbnail view it keeps the "Thumbs.db" file open. My simple way to fix this is this tweak to the registry, save this code in notepad with .reg extension then just double click it
Code: Select all
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Explorer]
"DisableThumbsDBOnNetworkFolders"=dword:00000001
