You can apply wildcard filter(s) when detecting changes and copying files. By default, the system will filter out hidden files, on Unix, that means files/folder starting with ".", on Windows, that means files/folders with "hidden" attribute. You may want to filter out, e.g. files with ".tmp" extension.

Note: filters are applied on both sides, source and destination (i.e. the workspace). E.g. if you filter out ".tmp" files, all ".tmp" files currently in workspace will not be removed.
