Having files out of sync causes issues when trying to apply actions on files that need to be synchronized. Since my understanding of synchronizing files has no direct effect on physical data (model changes), then why not having this automatically done for the user versus having them to do this manually every day. This is especially critical for third party CAD users, Solidworks and others, using the WWGM application, who have an additional local folder in Windows that displays their files in the active Workspace. This folder and the local cache for the Workspace do fall out of sync somewhat regularly due to connectivity issues between the CAD tool and the Windchill client app.
At a minimum, it would be great to have Windchill auto sync when launching the application or activating a Workspace.
