Why can't I delete files from SD card?

Try switching the grey button on the sd card adapter. sometimes it switches to lock and will not let you delete files. button must be pushed all the way left.

Hi Craig:

Put the card in your GoPro and erase it from there.

You could probably reboot your computer and try erasing files, but if this card is only used in your GoPro I would erase if from there.

Also see the following help file from GoPro. https://gopro.com/support/articles/how-to-delete-files-from-microsd-cards-with-h ero3plus

GoPro uses the card as a microSD in the camera, but in the MBP you need the sleeve/adapter. The adapter has a "wriite-lock" tab.

Also, GoPro has management software that likes to manage its own files and its own internal database of items on the card. You can "clear" the card from MBP but deleting individual files is not advised because the GoPro DB software was not involved.

Managing individual items on the GoPRo without the optional ($80) LCD screen is "last item entered" only. With the LCD screen you can select which files to delete and the GoPro will not be confused about its files.

Deleting from the GoPro is an inappropriate answer. It is not an answer. I don't want to use the go pro or other device. I want to use my Mac. I don't care if the SD card eventually corrupts. How do I erase and/or reformat from my mac?

Thank you; so simple yet so lethal; I would’ve went crazy all bc of that broke the computer; and card everything lol
