Can not delete corrupted folder

Question

Hi there,
I'm using SharePoint Foundation 2010 and am having problem with one of the site collections.
It's a simple 'Team site'. The problem is that I can not delete the certain folder, which seems to be corrupted.
Symptoms:
if I try to delete it I receive error "Access Denied", even though I use farm admin account.
if I try to 'Manage permissions', I receive error "Can not complete this action".
if I try to 'Edit Properties' (rename library) I receive error "Access Denied".
'View Properties' works good.
Looking in WebDav, the folder doesn't exist.
if I try to create a new folder with the same name within the same root library, I receive error that folder already exists.
Steps taken:
1. the entire site collection was backed up (using Backup-SPSite) and restored (Restore-SPSite) to the newly-created site collection within another Web App
and content database - the corrupted folder was carried over and the issue remained the same.
2. tried to use .NET methods to delete this folder but received error:
$rabbit = Get-SPWeb "https://site1.sharepoint.local/BD"
$damaged_folder = $rabbit.GetFolder("Services/Technical Team/Mit")
attempted to delete:
PS C:\Windows\system32> $damaged_folder.Delete()
Exception calling "Delete" with "0" argument(s): "Cannot remove file "Mit". Error Code: 16389."
attempted to move to Recycle Bin:
PS C:\Windows\system32> $damaged_folder.Recycle()
Exception calling "Recycle" with "0" argument(s): "Cannot remove file "Mit". Error Code: 16389."
Looking at the properties of $damaged_folder, I've noticed that property 'EffectiveRawPermissions' was blank, while for the normal folder it was set to 'FullMask'
I've tried to update it but received an error:
PS C:\Windows\system32> $damaged_folder.EffectiveRawPermissions = "FullMask"
"EffectiveRawPermissions" is a ReadOnly property.
Any help is greatly appreciated!

Answer 1

I am facing the same
problem.
I tried to delete the folder with a powershell command and with a console application. The result is :
Exception calling "Delete" with "0" argument(s): "Cannot remove file "Folder". Error Code: 16389."
At line:1 char:77
+ [Microsoft.SharePoint.SPSecurity]::RunWithElevatedPrivileges({$folder.Delete<<<< ()})
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException
The last possibility it's maybe to remove lines on the database!
Does anyone has triedthis solution?
Thanks in adavance.
