reload branch in "files" load mode.

Can I reload branch from server data after uploading, moving or copying files in some cases? I use loadBranch but after that I still see old data on view.

For such use-case, thebranch mode is preferable. Please check the detailed answer here: http://forum.webix.com/discussion/comment/14351/#Comment_14351

Is I can do nothing for this in “files” mode? Can I reload filemaneger colntrol? Load all data from server anew?

> Load all data from server anew?

Yes. Data can be reloaded as

$$('filemanager').clearAll(); 
$$('filemanager').load(url);
