In my LAN I have a main computer, the server, that shares a folder. Other users of the LAN can access to the foler and copy, modify and delete files. However, many times when the user try to delete a folder get an error that says that the file thumb can't be delete because the file explorer has opened the file. That's is not true.
The user has the needed permissions to delete the files, but for some reason he can't.
I know that one solution is to show icons instead of miniature in the file explorer, but it is not a solution in this case, because the user uses many photos and it's easier to see the miniatures instead of the icons.
How can I solve the problem and delete this file? Any easy and permanent solution? because this occurs in many folders and the user don't have a hugh knowledgement of windows.
Thank so much.
