The File Browser lets you manage system files and folders. It displays the filesystem on a tree view, and provides a native context-menu, which the same options as your system’s. You can access it from View > File Browser.
The File Browser has a filter functionality. You can define a list of masks separated by semicolons, such as *.php;*.xml;*.txt, and only files with a matching extension will be displayed.
To enable and setup the file filter:
- Click on the Filter… icon on the top of the widget. A dialog will pop up.
- Enter the list of file masks and click OK.
Warning: If your system hides file extensions for known filetypes, filtering will be applied to the filenames as they are provided by the system, without extension.
