Few days while I was still using Windows, I just put my index.php file in htdocs folder (run the servers previously of course) and that's it. Now I have the premade index.php file and some other stuff there, but I can't delete them or edit them. I get the read only. I can remove them with sudo rm and I can edit index.php with sudo nano but I want to be able to do it with regular text editor instead of terminal. Any ideas?
Thanks!

Change file and/or folder permissions.
