Guys, I'm doing some stuff on SD cards. I deleted a folder, then tried to copy another folder onto it, and there wasn't enough space for it. So I deleted everything off the SD card, but there still wasn't enough space. I gave up and put the card into a PC. That's when I realised what was going on... The SD card had a load of files beginning with a '.' on it. When I deleted these with the PC, the space was available again. So, it seems to come down to the fact that on my rMBP, I don't delete the files, I 'Move them to Trash'!! So, how do I delete stuff from an SD card with my rMBP? If I 'Empty Trash' will it clear the stuff off the SD card as well as the Mac? I'm not sure I want to empty the Mac's trash, but I certainly want to empty the SD card's trash - assuming it has one. Is there a way to just empty the SD card's trash? What's the best way to go about removing stuff from an SD card with a rMBP? Thanks.
