I remember trying to load a couple hundred MB text file in Notepad once, and I can't remember what RAM use was like, but CPU use skyrocketed, and it took quite the time to load. This was a Hyper-threaded Pentium 4 though. I think my Core 2 was much better, but it still took some time. I would guess with these sort of cases, you just have to wait (maybe you could let it do it's thing and walk away for a while).

Edit: If you can, try Photoshop for sure. It might be worth downloading the trial just to do this if it's bothering you that much. I just checked some of my PSD files, and my largest is apparently 655MB. It definitely doesn't take that long to open. I just checked by loading it and it only took like three or four seconds to load. I'm not sure if a file type difference with change this though.

Use the dbp plugin for gimp.
http://members.ozemail.com.au/~hodsond/dbp.html

Should be in a repository.

Guide:

FINAL EDIT:
You have 8GB RAM, open it in gimp. I always use x86_64.
If it doesn't open it is likely corrupt.

I hope this is not true.

Why does it take so much ram to open a 400mb file?

It's not true, but it will use a helluva lot of RAM whilst it's opening.

I had to use .txt corpus files (billions of words in use). Would take far more RAM than the actual size of the file while opening.

You could always password rar the file, send to thepiratebay (or similar, even dropbox) and let one of us DL it and resize it.

I can't imagine it would be a problem for photoshop as I have 4Gb PSD files I regularly work with

Because PNG is probably compressed, and what you see in an image editing/viewing program corresponds to an uncompressed image in your ram.

Try opening irfanview first, then go to Batch Conversion/Rename in the file menu. Point it at the file in the "Look in" box. Set the output format to jpg or whatever you want. Check the "Use Advanced Options" box and click on the Advanced button. Check Resize and check "Set long side to" and pick a length in pixels. (make sure "preserve aspect ratio" box is selected)

Pick your output folder and "Start Batch"

Not sure if this will work since it wouldn't open, but it won't try to load the image prior to running the batch conversion.
