Copying Files
Highlight a le and press “Enter” to select it. A check mark appears next to the 
le name. 
Navigate to the destination directory with the arrow keys, press “Enter”, and 
press F2 to copy the le. 
Note that les copied from the control’s memory to a device will have the exten-
sion “.NC”  appended to the le name. However the name can be changed by 
navigating to the destination directory, entering a new name, and then pressing 
F2.
Duplicating a File
Press List Prog to access the Device Manager. Select the memory tab. Cur-
sor to the program to duplicate, type a new program number (Onnnnn) and 
press F2. The highlighted program is duplicated with the new name, and it is 
made the active program. To duplicate a le to a different device, cursor to the 
program name and press F2 without entering a new le name. A popup menu 
lists destination devices. Select a device and press Enter to duplicate the le. 
To copy multiple les, press Enter to place a check mark at each le name. 
File Naming Convention
File names should be kept to a typical eight-dot-three format. For example: 
program1.txt. However, some CAD/CAM programs use “.NC” as a le type rec-
ognition, which is acceptable. File names can also be the same as the program 
number with no extension, but some PC applications may not recognize the 
le.
Files developed in the control will be named with the letter “O” followed by 5 
digits. For example, O12345. 
Renaming
To change the name of a le in USB or the Hard Drive, highlight the le, type a 
new name and press “Alter”.
Deleting
To delete a program le from a device, highlight the le and press Erase Prog. 
Delete multiple les by selecting them (press Enter to add a le to the selec-
tion and place a check mark next to it; deselect by pressing Enter again), then 
press Erase Prog to delete all selected les.
On-Screen Help
On-Screen help is available by pressing “HELP/CALC”. Select functions from 
the popup menu and press “Enter” to execute, or use the hot key listed. To exit 
the Help screen, press the “Cancel” button to return to the device manager.
