I have an external hard-drive formatted as NTFS which I use to back-up and store files from both Linux and Windows (as I am dual-booting). I recently bought a new computer and installed Linux Mint 20 on it, and I would like to copy some of the files from my back-up to my computer's internal HD. I noticed that every single file in every single subfolder I copied from the hard-drive has had the option Allow executing file as program enabled in its permissions. How can I safely recursively run through a directory and set all files in all subdirectories as non-executable (including hidden ones and in hidden folders starting with .)?
Also, is there a way of preventing this to happen in a NTFS hard-drive or would I be better off creating two partitions on it, an EXT4 for Linux and a NTFS for Windows?
