contents of wpo-minify folder

@francoc30 When you minify JS and CSS files from WP-Optimize WP-Optimize creates a folder wpo-minify and stores in it, the best way to delete the files is purgeing the minified files from WP-Optimize > Minify, do not delete it manually from filemanager or FTP.

@bornforphp What happen after I purge the minified files? Will they be generated when visitors visit the site or I have to run Preload Cache to generate all pages?
I saw from another post in this forum using some added code to limit the number of old minify files in the folder. This will save some server space. Will that works?
Also please answer all my queries and not skip over some. Much appreciated.

@francoc30 Once you delete the minified files it will generate again when users visit your site.

Could you please let us know which code snippet you are talking about?

The snippet below is to be added to the child theme function.php

add_filter( ‘wp_optimize_minify_cache_expiry_time’, function( $original_value ) {
return time() – 86400 * 3;
} );

Please confirm.

Yes this snippet is added to your active child themes functions.php file.
