Also view Centro Attributes via the Properties dialog window (see Display Centro Attributes).

Copy

  1. Click the Copy button to copy the metadata shown in the dialog box to the Windows clipboard in Text file format.
  2. Use the Windows paste command (CTRL-V) in your text-friendly application to capture/save the data.

Save

  1. Click the Save button to save the information to a file in one of three different formats: Text (.txt), CSV (.csv), XML (.xml).
