This page covers getting plg_system_rca_j2c_downfilessync onto your site, keeping it current through the Pro update feed, and removing it without surprises.
RCA J2C DownfilesSync is Pro. Download plg_system_rca_j2c_downfilessync from https://recreatinganew.com after purchase. The Joomla install element is rca_j2c_downfilessync. In Extensions, Manage, Extensions, the plugin appears as System - RCA J2C DownfilesSync.
Open System, Install Extensions, and upload the ZIP. Joomla installs the plugin under plugins/system/rca_j2c_downfilessync. Enable the plugin if your workflow leaves new system plugins disabled. Before you sync products, set J2Commerce Attachment folder path to your downloads root (parent of free/ and pro/) and align master variant SKUs with package folder names if you use Full Auto mode.
Install a newer Pro ZIP through System, Install Extensions, with method upgrade, or use Joomla Update when the private Pro feed offers a version. Versions 1.1 and later default to Full Auto sync; version 1.2 adds retail sellable-only rules and internal-only package exclusions. After upgrade, review Sync mode, retail options, and any Product folder map overrides, then run Sync Now on a mapped product before you announce a release to customers.
The plugin registers the Pro private update server at https://recreatinganew.com/extensions/private/feeds/plg_system_rca_j2c_downfilessync.xml. Your site must reach that URL with valid Pro credentials configured in Joomla’s update system the same way you use other RCA Pro extensions.
Uninstalling removes the plugin files and plugin parameters from Joomla. It does not delete J2Commerce product file rows. Whatever paths Sync wrote last remain in the database until you edit products manually or install a replacement workflow. Uninstall does not remove ZIP files from your attachment folders.
Back up the site database and the attachment folder tree if you rely on downloadable sales revenue, because product file rows are the contract between disk and checkout. The plugin upgrade itself is a standard Joomla plugin upgrade, but commerce sites deserve boring backups anyway.
