Hey! Me again. Sorry for the incessant posts but I just can't get enough of lua! Been programming my butt off.

Here's the code.
Spoiler

The error I receive when first running the code on a blank computer is this.
startup.lua:19: auto.lua: File Exists
The idea is to be installing a load of programs from the disk/CnS/ dir onto the turtle that's parked by the disk drive.
Afterward, if I check the list of programs under the CnS/ dir, auto.lua is the only one showing up.
There should be a few more than that.
I believe it's attempting to copy the program twice which is producing the error but I cannot for the life of me figure out where it's doing that? I need an extra pair of eyes if anyone is willing to take a look.

Thank you!

OH and don't get the wrong idea I still need help with my other posts! I've got a bunch of different projects that I'm bouncing between.

EDIT:
I've patched my bug but I'm not sure if this is the roundabout way or the exact way I needed to do it.
In order to fix it I simply put fs.delete("CnS/"..disk_commandList) right before the fs.copy(...) and that seems ot have fixed it.

The issue is that fs.copydoesn't like to overwrite files and you told it to do that, by deleting first you make sure that the file won't exist.

I understand that much but I'm still confused because when I would do 'delete CnS/' manually before updating it would still produce that error. Am I just blind?

There is no functional difference between deleting inside a program and deleting manually.
