Windows folders that can't be renamed or deleted
Windows generates hidden Thumbs.db files in folders with thumbnail-able content, but as of Windows 7 (maybe Vista, too), the OS doesn't actually need them; the files are only for compatibility with older Windows OSes and apps that make use of the files.
In Windows Vista and Windows 7, there's some kind of Explorer bug which sometimes holds these Thumbs.db files open, preventing renaming or deletion of their parent folder. It seems to mostly affect video files.
One workaround is this:
- Temporarily change the folder view to one of the following: content, medium icons, large icons, extra-large icons.
Another workaround is to disable Thumbs.db generation with a group policy update. There are various instructions around for doing this, but this is the simplest (do it as an Administrator, and remember you have to do Run as Administrator when opening the command shell):
REG ADD "HKCU\Software\Policies\Microsoft\Windows\Explorer" /v "DisableThumbsDBOnNetworkFolders" /t REG_DWORD /d 1 /f
You can then check the status of the key:
REG QUERY "HKCU\Software\Policies\Microsoft\Windows\Explorer" /v "DisableThumbsDBOnNetworkFolders"
After disabling Thumbs.db generation, you might want to just go ahead and delete all your existing Thumbs.db files (do it from the root of each drive):
del /F /S /A:H Thumbs.db
Here are a couple of discussion threads related to this:
One of the posts mentions the possibility that it has something to do with SMB2 Client Redirector cache, but no one seems to have checked into this:
