Earth Plot is currently coded to look for a file named "tle.txt" at:
/Users/YourUserName/Library/Application Support/Joyful Coder/EarthPlot

The tle.txt file contains the names of the TLE files you want Earth Plot to load.

The file can simply be a list of full path file names.

# Comment lines begin with a '#' character.
C:\Users\joyfulcoder\Documents\Earth Plot Data\iss.tle
C:\Users\joyfulcoder\Documents\Earth Plot Data\pegasus.tle
If all your files are in the same path then specify a path for subsequent files with a '>' character.
