Noob trying to first time navigate File Manager to delete ._ files

pjft

Unfortunately, I don't quite know much about Retropie's File Manager, but maybe we can try the following if you have a keyboard connected to your Pi.

Exit EmulationStation by pressing F4
Type the following commands:

cd RetroPie
cd roms
Now, navigate to each of the system folders where you have that problem, and remove the files. In this case, I'm starting with arcade, but other names are nes, snes, gb, etc.

cd arcade
rm ._.
cd ..

and then move on to another system.

Be very careful with the rm command, as it will delete all files that match the pattern. In this case, we're matching "._<anything>.<anything>" (note the "dots" and the "underscore" character that make the pattern for those files from your Mac).

Then, if you restart EmulationStation it should all be good to go. You may want to reboot your RetroPie:

sudo reboot now

A good practice is, in your Mac, before copying over the files, to remove them in your Mac.

Using the Mac terminal (in Applications > Utilities), navigate to your rom folders and run

dot_clean

Let me know if you'd have trouble doing that.

Best of luck.

If you're not comfortable running scripts you can also just search in Finder for "._". Right-click and delete the files.

rm ._*.*

To do all folders -

rm -rf ~/RetroPie/roms/*/._*

rm -rf ~/RetroPie/roms//._

Thanks for the Unix clarification.

A question: would ._* also include files with extensions? (i.e. how strict is Unix with matching the asterisk character - do we need ._*.* ?)

Cheers!

BuZz

@pjft It would. It will delete anything in any folder in roms starting with ._

I assume you meant ._* and not .* - you need to use inline code markup on this forum or info will be lost as styling.

pjft

@BuZz Got it - yes I did. I'll edit that. I struggled to use back-quotes with my current keyboard layout until recently. :)

I believe DOS did only match empty file extensions if we omitted the last (.*), hence the question.

Happy Easter weekend everyone!

BuZz

@pjft Yeah - dos treats extensions differently. Unix doesn't really have "extensions" in the same way - it has filenames, which can contain various characters. you can have lots of dots in a filename if you want for example.

@BuZz So do I type in:

rm -rf ~/RetroPie/roms//._

While in the File Manager or after pressing F4 to exit out of Emulation Station?

BTW "THANK YOU" EVERYONE - I REALLY APPRECIATE IT!!!

pjft

@ClarkNova I don't know how the file manager works, but yes - if you exit EmulationStation to the command line via F4 and run that, that will work.

Do make sure to use the right command, though :) Copy exactly the one from Buzz, with asterisks and dots.

ClarkNova

@pjft I'm holding F4 while it boots and I'm still taken to the Emulation Station.

pjft

@ClarkNova sorry it wasn't clear. You press f4 when in ES. Or alternative just navigate to the menu and select Exit ES.

Use Buzz's command exactly as it's spelled.

Okay, it looks like I have it running pretty clean now. Thank you all so much. Next I'll try to figure out how to add Famicom CDS, Super Famicom, Virtual Boy and maybe Game & Watch directories/roms to my build. Time to start hunting through the threads [slaps and rubs hands together in eager excitement] :)
