This would allow a user to migrate to a different system if needed, as all of the files in an album would be in a proper folder. If a board had several thousand pictures, it could take days of clicking through each image, saving the high resolution copy to a folder on the local machine. If this was already set up, an admin could simply download the high-resolution pictures via FTP and have a complete set ready to be uploaded elsewhere, saving days of work.
