70 File Names
To avoid confusion,
don’t duplicate file
numbers. File numbers are used to identify which file is to be played in
response to Select File commands. File numbers contained on a drive
should be unique, regardless of the file type. In other words, you
shouldn’t have PLY00002.LST and VID00002.MPG on the same
drive. The two files should have different numbers. If more than one
file has the same number, the first file found in the directory will be
used.
The order of precedence for file execution is:
1. Schedule
2. Playlist
3. Video
4. Image
5. Banner
