[duplicate] Allow changing diff tool for some files

[Nux]

I like TC text comparison and use it very often. But comparing images as text/binary is not useful in most cases.

There are free tools for comparing images and it would be nice to have an option like "for extensions [.abc, .def] use [c:\image-diff.exe %T%N %P%N]". Where text in brackets would be user changeable of course.

Preferably at least 5 groups could be defined. Note that doc, odt and other office files could also be compared in a more medium-specific matter.

Oh. I added "%T%N" and "%P%N" in above example to keep the same format as for TC buttons. So you could use the same pattern parsing rules.

Sorry, I see it was discussed before:

Define the external compare tool in TC
and use something like Beyond Compare which does the rest automatically.
In my case it is
CompareTool="%COMMANDER_DRIVE%\tools\Beyond Compare 2\BC2.exe"
Then you can use a button or hotkey to invoke the external tool.
