I have reset my phone (Microsoft Lumia 535) due to some reasons. I saw that there is a huge Folder named WPsystem in my SD card. So I think these are apps and other data which installed by me. So now I think I do not need them because now system is clean and I have to install the apps again.
But I can not remove the WPSystem folder. I tried with a card reader. First it deletes perfectly. But when I put the reader back it haven't delete. I also tried to format the SD card. But it says "Windows can not format"
So how can I fix this, I want to remove the WPsystem folder.
