native icon for graphic files if Irfanview is portable

[covo]

TC shows correct/native icons for graphic files in standard version of Irfanview (icon is from Irfan).
But not for portable version of Irfan - it shows white icon, "any" icon from system/xp.
Any ideas for fix it?

But not for portable version of Irfan

that's because portable apps don't use the registry.
the best way to integrate portableapps in totalcmd is by using the "Internal associations".

have a look at:
