Here is a question for server admins. If a file is copied to a directory on the server, and a file already exists in that directory with the same file name, the user is presented with a dialogue box asking if they want to replace the existing file with the new one. Is there a directory permission setting that would allow immediate overwrites of existing files without presenting the "file already exists" dialogue box to the user?

In my case, an unattended desktop machine is creating and copying the files via s script to a couple of directories on a server. If the file is coming from a particular "user" signed in at that desktop, I'd like any existing file on the two server directories to be immediately overwritten, and not get the dialogue box. If the file is being copied from that machine, then in all cases it is OK for the existing file to be overwritten. An unanswered dialogue box stops the desktop from copying any further files until the "OK" button is clicked. I'd like to eliminate that hold-up.

Any ideas on this would be appreciated.

"copy /Y" overwrites without prompting

Thanks for the advice. I should have been more specific - the desktop computer making the files ia a Macintosh and it is creating the files in Photoshop via a Photoshop action (script).

At one point the files went to the server without invoking the file overwrite confirmation dialogue box. That's why I was wondering if perhaps a change to the permissions on the destination folder would cause the dialogue box to start appearing.
