This is not a bug. IviewAdditionalTypes is just for ADDITIONAL file types not detected internally. Files which do not have a valid header for that file type will not be passed to Irfanview.

How about some solution for problems alike form above link?
I think, TC should allow user to change something of this:
1) default lister supported file types (enable/disable them by extension);
2) possibility to add new header (hex string) for recognizing default supported formats;
As I understsnd, Lister in now checking header if file has supported extension.
3) allow to change priority between internal supported formats, IviewAdditionalTypes and plugins (like this implemented in Universal Viewer by Alextp);

I will try to find a solution, thanks for your suggestion.

Should be fixed now, please test!

Works fine for me in TC 7.01.

DrShark, do you agree?

[DrShark]

Yes, it works!
I created this parameter for test:
IviewAdditionalTypes=*.jpg *.swf *.dxf *.djvu
Only *.swf wasn't shown. Maybe the reason is that this IrfanView plugin creates it's own window for player...

Indeed you can only show image formats where irfanview converts the file to a bitmap and then displays it. It can then also send that image to Lister. SWF isn't a single image, it's more like a video...

[DrShark]

How TC/Lister detect what format is a picture and what is movie/music/etc? I mean... IrfanView supports a lot of formats... and often some new formats with new versions!

[ghisler(Author)]

It doesn't - if you use IViewAdditionalTypes, TC passes the file to Irfanview, and if it gets back a bmp, it displays it. So it all depends on Irfanview (or Xnview) whether you will get an image back or not.
