The destination can be either a device or a file. The file has to be named as TEMPFILE, and it will be created in the XTGOLD directory. Therefore if you wish to keep the file you must rename it, otherwise it will be overwritten the next time you print to a file.
Any valid device can be specified as the destination. This includes the parallel ports LPT1 to LPT3, serial ports COM1 to COM4 and PRN. If you wish to view the file on screen you may specify CON, although the file will probably scroll too fast for this to be useful. Better to use TEMPFILE and then View this.
The destination entered is treated as a configuration item and is remembered by XTree even when you exit the program.
