[FEATURE REQUEST] Compare left / right path files with external compare tool

[asdfasdf]

I am very much missing the ability to compare differing files on the left and right path using an external file compare tool.

This is very useful in programming, comparing source code files, text files, etc...

I suggest a new context menu command when files exist on both sides: "Compare files"

and it simply calls an external file compare tool using parameters <path_to_comparetool.exe> <LeftFile> <RightFile>

The external compare tool would be specified in settings.
One example tool is the WinMerge https://winmerge.org/downloads/?lang=en

This is already supported. In fact I use Winmerge to do specific compares myself. See Tools => Options, and Customize Context Menu.
