delay in explorer when selecting root folder in left pane

[davetest]

Hello,
my second hard, I:, has a 4 or 5 second delay before the folders
appear in the right pane. This happens if I use the
Explorer from the start button (right click/explorer).

If I create a shortcut to explorer on the desktop using the
following :
%windir%\explorer.exe /n, /e, /root, i:\

so that this instance opens directly at the I: drive,
the full display is instantaneous.

Are there some known delays in explorer that I could invesigate?

Thanks,
Dave

Your command is incorrect. /n is not valid with /e, /e implies /n. /n is
used to open a new window of a folder that is already opened in another
window in folder view. And technically there should be no space before i:\
but not that it matters.

Because you are rooting it it doesn't need to enumerate all the namespace
extensions in the left pane. The left and right panes are completely
different. Things only exist to windows when they are opened in the right
pane. The left pane is a bit of a hack. This is just a guess.

Thanks for this response. The command I gave works fine, that's not
the problem - I only gave that as an example that when that shortcut
is used, Explorer as well as the contents in the right pane appear
almost immediately.

Contrary to this, when I use the explorer from the start button,
and get the full "my computer" view (default) and click on the I:/
drive - it takes about 5 seconds until the contents of "i:" apppear.
Why this discrepancy ?

I found out the cause of the delay. in the root folder of the
I: drive I have a 200mb zip file containing about 300 files.

I moved this zip file to a sub-folder so that it is effectively hidden
when I: is selected. Opening is now instantaneous again.

Is XP doing some kind of interrogation of the zip delaying the folder
view from appearing?

Even if it is, why does the separate shortcut for I: that I mentioned
earlier *not* experience this delay?

It turns all zips into namespace objects (eg like My Comp, Recycle Bin,
etc). Each zip is treated as a folder. Zip files store the table of contents
at the end of a files.
