    Hello

    I'm getting a weird issue with Downloads folder. It takes 5-10 seconds under the message "We're working on it" until it's fully loaded. I don't have much files in there (80-90) so I don't know why is the load of that folder so slow. I went to folders that have more files than Downloads and files are shown inmediately.

    I'd ran DISM Health Checkup and SFC and there is no error in Windows files.

    How can I fix it?

    Thanks

    If you have a hard disk, try defragmenting it. If you use third party antivirus, try disabling it.

    Explorer is taking too much of your CPU on folders with many files or subfolders.
    You can compare with opening the folder with an alternative tool like Total Commander and see the difference.
    You might get partial results by disabling the search indexing for the Downloads folder which could be inconvenient and/or disabling antivirus scanning of the folder and subfolders which again may be problematic.
    Even with Defender or another antivirus and indexer disabled, you would still not resolve the issue entirely which has something to do with Windows Explorer.
    You can monitor this activity with Task Manager, Process Explorer and Resource Monitor and try to identify other possible causes.

    That is one of the reason I started tweaking, simply opening a file explorer caused this and left me hanging. Removing Network icon from explorer helped and I guess disabling scanning for other computers on the local network (there are none).
    Downloaded files are usually compressed (7z, zip, etc), it might trigger AV to check them first.

    Antonio, can you add explorer.exe to windows defender exclusions and see if it stops the slowness?

    Very strange. May be you should try rebuilding the index again. I'm not sure this can be helpful but these types of issues mostly get resolved by hit and trial. Have you checked your event log?

    I was looking at @murphy78 script linked by @Enthousiast and it tries to repair the Icon Cache in the current user's profile.
    Would you be able to use the built-in Administrator and browse to the same folder and check if it has the same issue.
    I had/have this issue as well and I am intrigued by the cause.
    It can be easily reproduced on the folder C:\Windows\servicing\Packages by keeping it open while trying to uninstall an obsolete/superseded package with DISM.
    Explorer scans the folder continuously and runs at 50% CPU while DISM takes the other half or so.
    It eventually finishes but may take 10 minutes.
    A workaround is to close the window with that folder which contains a large number of files.
    I experienced it on Downloads folder too, same thing in common is having many files and folders within that folder.

    well, you can try process explorer and see whats lagging when you browse that folder.

    Explorer is scanning in real time because the contents of that folder keeps changing.
    I think it is only an example of inefficient coding.

    You should also check with CrystalDiskMark for the actual Speeds of your SSD!

    I had once an SSD with such problems which had Read problems, even Write was ok and CrystalDiskInfo was even showing a 100% Health!. Finally, I had to claim that SSD from Samsung to get everything to work normally.
