Can't delete files

When I click on load and then try to delete my cut files it gives me an error code. I can usually go in and delete a file after I make my cut. My machine is starting to get a backlog of cut files now. I think the error code is 3. Anyone else have this issue or am I just overlooking something?

Check and see if your files are “read only and or administrator”


Are you saving to USB or to internal memory?
