Why is my memory card write protected by my Sumsung grand prime plus android 6.0.1?

[Android Central Question]

The folders and files can't be deleted. I want to remove the write protection.

Welcome to Android Central! How are you trying to delete the files? MicroSD cards don't have a write-protect switch on them (like fullsize SD cards), so this often suggests the card is getting corrupt. If you've already backed up any important data for that card, insert it into your computer and see if you can delete the files and folders using Windows Explorer (or just reformat it).

Hi sir I have the same problem about deleting the files from my micro sd card with the same samsung unit. Sir I already try what u have said but it didn't work. It said that my card is write-protected. Even if I try to format the card the operation will fail. Sir what will I do? Please help.
