I've had this from a reader and I'm stumped....
" a home-built machine based on a 2.4 GHz Athlon with 1 GB RAM running
Windows XP Home.
I do a lot of digital photography and have directories sometimes holding
several hundred jpegs, typically
~ 1.5 - 2 MB each. When I open such a directory in Explorer (I prefer just
to list files), it takes forever to read
the contents - the icons take about half a second each to change to the
default Photoshop icon, and with several hundred
files this can take three or four minutes in total. Meantime, I can do
nothing but sit and wait for this to complete -
Explorer freezes until all icons are updated. I also have a 1 GHz laptop
with 640 MB RAM running Windows
2000 Pro, and these directories open almost instantaneously - the icons
update in milliseconds."
He's tried virus checking, defragging and, at my suggestion, rebuilding the icon cache. And note that he's in list, not thumbnail view? Ring any other bells with anyone?
