Inputting and Outputting Media > Processing and Publishing > About the Publish Menu Options >
Output File Management Group

Use the Output File Management options to control the destination of published media.

Create Subdirectory button
  Enable to create subdirectories in the following format: /basedirectory/clipname/tapename/resolution. The Create Subdirectory button is available when Publish Type is set to Complex or Flatten.
Published Clip Name Extension field
  The value in this field is appended to the name of the published clip in the library. The default is _published.
Destination field
  Enter the destination path of the file, which is usually the location of the shared storage. By default, the destination path is /usr/tmp.
Link button
  Enable to link the published clips to the original file, located on the same filesystem. A link at the filesystem level is created to the media already on the destination filesystem, which saves space because the media is not duplicated.

When you publish media from one filesystem to another, the media is copied even if the Link option is enabled. If you are publishing some media from the same filesystem and some from a different filesystem with the Link option enabled, any media that is on the same filesystem is linked to the original media. Media that is on a different filesystem is duplicated.
