Attachments – Manage total space per user/role

Currently you can set how many attachments can be sent with a message, also attachment size can be set. Also you can set how many messages can a user keep in his messagebox. So with this configuration you can easily control your space.

Thanks for responding. I have already seen these possibilities in the settings. They allow a relative control, but they are not a real solution in my opinion. So I’ll do it manually, e.g. the 1st of November I am deleting the folder for September and so on.

You can add a cron job to automate this process. add following code in your theme’s functions.php

add_action( 'init', 'fep_cus_schedule_event' );

function fep_cus_schedule_event() {
    if ( ! wp_next_scheduled( 'fep_cus_schedule_event' ) ){
		wp_schedule_event(time(), 'daily', 'fep_cus_schedule_event');
	}
}

add_action( 'fep_cus_schedule_event', 'fep_cus_remove_older_files');

function fep_cus_remove_older_files(){
	$wp_upload_dir = wp_upload_dir();
	$upload_path = $wp_upload_dir['basedir'] . '/front-end-pm';
	
	if ( get_option( 'uploads_use_yearmonth_folders' ) ) {
		$files = array_filter(glob("{$upload_path}/*/*/*"), 'is_file');
	} else {
		$files = array_filter(glob("{$upload_path}/*"), 'is_file');
	}
	$now   = time();

	foreach ($files as $file) {
		if ($now - filemtime($file) >= 3 * MONTH_IN_SECONDS ) { // 3 months
			unlink($file);
		}
	}
}

It will delete all files older than 3 months. Also please note that if somebody send a message with attachment and later find that his attachment is gone he may find it uncomfortable or may damage valuable information.
It will just delete attachment files not other attachment data but if anybody go to download that attachment that time full attachment will be deleted including other attachment data.

I really appreciate your help. You are exceptional. Thank you very much.
