Putting Bird files on New SD

I was able to change my lowrance files to gpx and put them
on the hummingbird program but am having trouble getting them from\ pc to new card.. Any thoughts

Hi wllye – just find the file on your computer, highlight the line by left clicking the mouse on it, then right click the mouse on the line and select “send to” and select the drive that is for your SD card and you will be good to go.

it says the disc is write protected?

looked write protected up on the internet and someone said
put tape over the lock switch on the side, and I’ll be darned if it didn’t work.. amazing. thanks for your help
