Copy a file from a plugin into my theme directory

To answer your question, you have specified the paths incorrectly: plugin_dir_path( __FILE__ ) already has a trailing slash at the end (having two trailing slashes should not be a problem, but safer is to have one) and get_stylesheet_directory() comes with no trailing slash at the end, so you have to add one before adding the … Read more

Convenient way to use wp_filesystem

No, there is not a more convenient way.

Standard location for plugin to save/cache files?

It would be nice if WordPress had a standards based cache directory, but since it doesn’t I think the best option is to keep it in the plugin folder itself. Uploads are in my opinion for actual uploads and cache files are not really considered as such. I think it easier to manage , reduces … Read more
