Tools - Settings - Programs -
Under "Tools → Settings → Programs" in the tab "Compare files", the user may define programs for comparing two text files, depending on their file extension.
Assignment of filters and programs (compare files)
Different file extensions (in the column "filter") may be assigned to different file comparison programs (in the column "programs").
In the above example, all files are assigned to the program "PSPad.exe".
Calling the text file comparison
The menu item "File → Compare files..." or the hotkey "Ctrl+Alt+V" compares two selected text files. These two files may be located in the same panel or in two different panels.
If two or more text files are selected in the active panel, the first two files will be compared: %FileCompare1% will be replaced with the path of the first file, and %FileCompare2% with the path of the second file.
If there is only one file selected in the active panel, %FileCompare1% will be replaced with the path of the selected file in the left panel, and %FileCompare2% with the path of the selected file in the right panel.
The following buttons are available for editing the list of filters and file comparison programs:
The input box "program" specifies the program which should perform the action for the highlighted row.
The input box "parameter" specifies any parameters required for the program in the highlighted row.
