Do you want to free up some space on your hosting server? Need increased security for attachments? Switch to Filestack! The WordPress uploader works great. If your users attach a lot of files to their tickets and replies however, you can quickly reach your disk space limit. Especially if you’re on a shared hosting. This add-on replaces the default WordPress uploader used for attachments by Filestack. This means that the files that are attached to tickets are no longer taking space on your server: everything is stored on the Filestack infrastructure.
