Folder display query

[pjp]

I have a folder I've been filling with Nero Image files (nrg extension).
Each is approx 4.5 gig in size. I started noticing an extremely long
delay before Explorer would display the contents of the folder when I
navigated into it. I suspect it was some background task trying to
ascertain info from the files. To test, I simply created a new sub-
folder and moved most of the files into it. Sure enough, Explorer then
displayed the folder quickly when only had 2-3 files in it and also it
displayed the sub folder slowly with a long pause with 20 or so files in
it.

Question is, is there anyway to determine what sub-process is causing
the long delay and maybe someway to tell Windows to just treat it as an
"unknown" file; least in respect to displaying it in Explorer?

I'd guess that you've got the view setting for something like "large
icons". That will take time to generate with files as big as that.

Nope happens everytime I enter the folder regardless of the view when I
exited it last. I figure it's trying to ascertain some info from each
file same way as avi files display dimension and length and with the
files so large it takes way too long for basically nada. Therefore
wondering what little process is trying to do that and then perhaps
there's some way of telling it not to.

Maybe it's a virus scanner? There have been viruses that used Explorer
bugs to infect computers simply by reading the icons.

Right then. Task Manager. Load it, Processes tab; let Explorer enter the
folder with the big pics, see what process becomes active under the CPU
heading.
