SVN File Editors Preferences
Each type of file is associated with a type of editor that opens the files of that type for editing. The editor can be the built-in one specially provided for the file type (for example, the internal XML editor, the internal XSLT editor, the internal XSL-FO editor, etc) or an external application installed on the computer, either the default system application associated with that file type in the operating system or other particular application specified by the path to its executable file. To configure SVN file formats, open the Preferences dialog box and go to SVN File Editors.
SVN File Editors Preferences Panel

The Edit button or a double-click a table row opens a dialog box for specifying the editor associated with the file type. The same dialog box is displayed on opening a file from one of the Syncro SVN Client views.
Open With Dialog Box

In this dialog box are offered three options for opening a file:
- System default application - Opens the selected file using the application that is associated with that file extension by default in the operating system.
- System application - Opens the selected file using an external application that you have to specify by the path of its executable file. Also, you can specify some arguments for the command line of that application, if they are needed. This option also works for directories, if you want to choose a file browser other than the system default.
- Internal editor - Allows you to select an editor type from the built-in editors that are included in Syncro SVN Client. By default, this option is disabled when selecting directories.
If a file type is associated with an internal editor other than an XML editor type then the encoding set in the preference for Encoding for non XML files is used for opening and saving a file of that type. This is necessary because in the case of XML files, the encoding is usually declared at the beginning of the XML file in a special declaration or it assumes the default value UTF-8, but in the case of non-XML files there is no standard mechanism for declaring the encoding of the file.
