Two folders on a file server I administer had been created with a space at the end of the folder name.
If I tried to delete these folders I got the message “Could not find the item”
If I tried to view the security I got the message “The requested security information is either unavailable or can’t be displayed”
I found is was possible to delete the folders via a CMD prompt using the command;
rd “\\?\C:\path to bad sub dir\bad dir “
