I have a cron job that alerts me to modified files on a couple of WordPress installs. Two of them alerted me tonight to the creation of apparently empty folders like
/home/foo/public_html/wp-content/uploads/2013/05
Is there a scheduled job in WordPress to create the next month’s upload directory on the last day of a month?
I believe by default these folders are created by user interaction, however, it’s possible that a plugin may be calling a function to create these monthly upload folders.
That’s according to the the Codex > Function Reference >
wp_upload_dir()
. Maybe you could get more detailed logs to determine how they’re created…I’m not real familiar with server administration.
