Browse Server
If you are going to add an image or create a link in the text editor, then you can click on the "Browse Server" button. A new window will be displayed with a file browser. Below is a brief description of the functionality:

-
Files path / location
Here you can see where the current files list is located.
The file icon shows the type of files that is currently listed. In some cases you will be able to change this filter when you move your mouse over the icon and choose another option.
Quick tip: click on a folder name at the top to go to that folder directly.
-
Search
Fill in (a part of) the file or folder name and click the button to find your file or folder.
-
Tabs "File info" and "Upload file"
File info: By default, this tab is selected and shows the details of the selected file (listed blue at the left side).
Upload file: Click this tab to switch to the upload mode. Doing so, you can upload multiple files at the current location. After the upload is complete, the file(s) will be listed at the left side. You are able to select the new uploaded file right away.

Selected file
Here you can see which file is currently selected. This file is also listed in blue. To clear/remove the selection, you can click the gray cross icon, or just select another file.
