How to delete NTFS read-only files?

There is info on file permissions here

Scroll down to the section explaining the use of rm -rf /path/to/stuff/to/delete - Be careful it will delete inside the folders and is not undoable. You may also need administrator privileges.

You can use Applications/Utilities/Disk Utility to erase the second drive if you want to, it will delete all the data on the disk, so backup what you need if you decide to do this. Try the help menu in disk utility, since I cant see any erasing guides on apple.com

You should be able to delete them, and be prompted for an administrator password when you try. However, you can get information on the files (right click --> get info) and at the bottom click the lock to authenticate, and then change the "everyone" permissions to "read & write". Then try removing the files.

They are probably locked. Check in Get Info.

Great, I'm glad it helped thanks for the star 🙂

PS Terminal is a little scary, but very powerful.
