.TRAY File Extension
What is a TRAY file?
File created by Corel CONNECT, a graphics content organizer that is part of CorelDRAW Graphics Suite; stores a user-selected group of graphics and can include both raster and vector samples; used for storing image trays that can be recalled.
The graphics in trays can be imported into CorelDRAW or Corel PHOTO-PAINT.
NOTE: Corel CONNECT creates one TRAY file per user tray in the [user]\Documents\Corel\Corel Conten\Trays\ directory. The user does not manually save TRAY files, but you can open a shared tray by choosing the "Open tray file..." option from the tray panel.
