The file/folder attributes for the Xampp and all sub-directories are set to grayed-out read only, etc. I am running a sub-routine called Gallery located in the htdocs folder. In order to update Gallery, that subroutine needs to add/change sub-folders in the htdocs folder. Because the folder attributes are grayed out, I cannot make the directories read-write so Gallery cannot update itself. It seems these settings are set by some user other than Admin since when I log in as Admin, I don't have change rights. How can I make those htdocs sub-folders read-write?
