Once in a while we see a behaviour in our Windows 7 systems that is a bit puzzling.
While working on a Win7 VM creating our PDF invoices the local Windows 7 workstation where they are e-mailed out from does not see the file at all in Windows Explorer.
Yet, if the filename such as “Invoice 12345 Client.PDF” is punched into the Search field the file shows up as being there.
If the file in the search result is double clicked to open or copy there is an error stating that the file does not exist! Click the X to the right of the search term and the file is not listed there after the search either.
After much research we have figured out what we need to do to reduce the likelihood that the behaviour will happen, or if it does happen the time for the file to show up is greatly reduced.

- Posts on this forum topic are very informative.

The last one has an explanation of all of the registry settings.
We will be configuring the registry settings into our Windows Computers Policy GPO with reduced time settings to see if the changes make a difference. When waiting for the file to show up in Windows Explorer it sure does not seem like 10 seconds!

Hello, do you have any updates on this issue? We're seeing this on a few clients at different jobsites, specifically with scans. We have one site scanning to SMB and another site scanning via FTP same result on a couple clients they scan and they don't show up...even after a refresh. A restart and they show up.
