Access Denied trying to delete FSA placeholder

Hi There,

I am trying to delete a folder no longer required on a shared data location.
The folder location is on a NetApp Filer CFIS share.
FSA has been disabled for this location but it has left some files with a Grey X on the icon.
We have also suffered from some data loss in the backup Archives which means the original file is no longer available to be restored.
I have tried using both my Admin account and the EV Service account from both a File Services Admin Windows Server as well as the EV Archive server\r, but both accounts return an access denied eroor when trying to delete the file.

Any advise would be great.

Thanks for your time.
