I examine the following code I hooked into the Network/Sites list table:
<?php echo get_blog_option($id, 'upload_path'); ?>
<?php echo get_option('upload_path'); ?>
Most sites, but especially my most recent blogs echo something like "wp-content/blogs.dir/219/files". I presume this is normal, and end users can't change this.
However, a couple of my oldest blogs echo "wp-content/files".
And several others echo "wp-content/uploads".
I am running latest WP3.5.1 multisite, but it is on top of an install that is subfolder install I have faithfully updated since 2006. Any files uploaded on any of the sites seem to correctly go in and out of the blogs.dir as expected.
Is it ok that I get this variety of values for the upload_path option? If not how to I change them? Which format for upload_path is correct?
