I have a small problem. I don't want that our Macs here create the ._ files to the network drive. For example when you copy an image over the finder to the SMB storage.

Is there a way to disable this function in Finder?

The .DS_Store file is already disabled, but not files such as ._pic1.jpg .

We activated veto files in samba to prevent creation of ._ files, there arose an error – not enough permissions on the drive.

Thank to all ;)

Finder does much to ensure integrity of data, and to make its results compatible with a broad range of Apple operating systems.

Please, you should not attempt to prevent Finder from creating ._ (dot underscore) files during copy or move routines.

File system

If you prevent creation at the file system level – as you did with your configuration of Samba – you make that file system partially incompatible with at least:

  • Apple Finder
  • Microsoft Office Excel, PowerPoint and Word 2011.

(For any use case that involves Office 2011 saving to a file system, you must allow ._ on that file system … and so on.)

For more detail please see my answer to a more recent question, Why are dot underscore ._ files created, and how can I avoid them?:

    Thx. The post is a bit older and there is no way to prevent it. I have made a script which delete this files. Commented Jul 27, 2012 at 7:20

Don't know of a way within Finder, but Blue Harvest (paid application) offers this functionality: http://www.zeroonetwenty.com/blueharvest4/
