Can't delete files from a micro SD card from a phone

[mainachan]

Can't delete files from it even using pc or through the phone. Says something about write protection or something. There is no switch on the micro sd and I do not have sd card reader. I tried the long path tool but it doesn't work because when the phone is plugged into the computer, its not located under computer so its no point. Any solutions?

Do you have any security apps installed in your phone. Check and see if you can turn-off write protection or read only access in every app you see that relates to your phone security.
