Is there an article for using the RTC Visual Studio client to download files
One answer
Yes, see https://jazz.net/library/article/87556 It is also in the documentation: https://jazz.net/help-dev/clm/topic/com.ibm.team.scm.doc/topics/c_working_in_vs_client_scm.html
All those are searchable e.g. use the library menu to open the articles or the documentation and then search e.g. for visual studio or search Google for 'SCM visual Studio' and add site:jazz.net to limit search on the site.
