Directories littered with invisible files

[k6lcm]

I have run across an issue when manipulating the SD card for my BMC64 build in macOS. Whenever I copy files in the Mac Finder to the various directories on my BMC64 uSD card, two files appear in the directory listing when viewing it on the BMC64. For example, if I copy gianna_sisters.d64 I will also get a ghost file called ._gianna_sisters.d64. Note that these file names begin with a dot and an underscore.

I have tried viewing invisible files on my Mac (command-shift-period) but they neither appear using that method nor performing an ls on the uSD directory in the Mac Terminal command line. I can see other normal invisible macOS files like .Trashes but I can't see these dot underscore files. It seems like only the BMC64 system is seeing them. Loading and running these files yields an error.

This is something MacOS does and BMC64 does not filter them like your OS does. You can clean your directories using a program called 'dot_clean'. See stackexchange post:

https://apple.stackexchange.com/questions/14980/why-are-dot-underscore-files-created-and-how-can-i-avoid-them

I can add a filter I suppose to hide them like the OSs do.

Thanks @randyrossi! That makes sense. I had heard about .files but not ._files. Thanks for the reference. Not a huge deal but a filter would make things easier for us macOS users. Meanwhile, I will check out 'dot_clean'.

Thanks for all of your work on these projects. I am loving the vicii-kawari on my real hardware.
