XnView Software

I wish I had kept my old ACDSee, in this regard it was lightning fast! But unfortunately it crashes to often.

Now trying IrfanView.

Hello!

I have XnView 2.33 and it starts very slow to the browser, when I try to open my main photo-folder with 15000 images. It almost takes 2 - 3 minutes to show me the thumbnails.

What can I do? As it is now, it is unusable.

Thanks in advance!
