if suspicious of files in installation, can install component again, overwrite existing files , replace them copies of component? perspective, represents substantial time saving on investigating each file if reinstall component suspicious files, and/or plugins/modules/joomla.

then left files not part of usual installation investigate, , can more sure potentially dodgy, can rename them , investigate.

would methodology work, or should process via ftp?
