Win10pro

When accessing a folder I get a green line crawling along the top of
the screen that often takes a good minute to go from left to right.

This never happened before. Can this be switched off?

The next time, check the thumbnail databases. Open the folder
with the thumbnail databases in it first, then open your personal folder
and watch as the thumbnailer does a traverse through the
directory. Then see if the thumbnail databases changed in
size or not. That's a quick way to confirm what it is.

At one time, I thought that was some kind of "TakeOwn" traversal,
but now my theory is that it's a thumbnail run. You can track
it down for us...

You should be an expert on that thumbnail issue by now. We've
had a few discussions about this in the past. (Specifically,
Adobe PDF thumbnails, the slowest thumbnail flavor of all.)

When the thumbnailer runs, of course Windows Defender has to
scan each of those files as well. And if you're not careful,
each time the thumbernail database file is updated, it should
trigger the Search Indexer to reindex the file. In football,
we call this "piling on", in an attempt to crush the player
at the bottom of the heap.

Windows is examining the files in the folder and creating appropriate
icons and/or thumbnails for display. This is a one time process, unless
you use CCleaner or disk cleanup to remove thumbnails, in which case
they will be created again next time you view the folder.

I don't use any cleaners like that, and it *still* happens to me.

When I see the green line, I head to the kitchen to make coffee :-)
The time is not wasted. There's a lot of pots of coffee though.

I'm not sure, but I believe that the green line also occurs if you are
doing a search and the drive is not part of the Windows indexing process. I
would suggest that you hit the search icon and search for 'indexing
options'. Usually the default is only the C:\ drive. If you have any other
drives add them to the list of drives to be indexed. If you don't have any
other drives you might want to check to see if Windows Indexing is turned
on. Some people believe that turning it off makes their system more
responsive.


But when you're just opening a folder, the thing
is not doing a search. It has no reason to traverse
the folder.

It could be a thumbnail thing.

it could be a perverse attempt at mspmeng doing
a scan of the folder tree.

Using ProcMon might tell you, which of those possibilities
is most likely.

The same green line can occur opening a network shared folder drive.

I've often seen that line at the top of a window, never the screen. It
can be very slow.

If you've installed Fall Creator's Update and this is when the problem
began then read this:
