When working with show files originally created with older versions of the Hog 4 OS or Hog 3 OS it is sometimes beneficial to optimize the show file's data to take advantage of the latest methods used by the Hog 4 OS to compress and store show data. Running the compress show utility can sometimes help to significantly reduce the size of a show file, improve log on/off times, speed up show backups, and/or improve network reliability.
Setup → Shows → Current Show
Click compress show.
The console will now scan the look data in the show (cues, palettes, scenes, etc.) and re-write the data in the show file using the most current and optimized methods utilized in the Hog 4 OS.
