Speed Up Folders with Videos if They Load Slowly

Windows 10 frequently performs optimization in the background and that can cause File Explorer to be slow when loading some folders, for example video folders:

If this error occurs when trying to access a specific folder, you might want to change that folder’s optimization.

This is rather simple and you can do it by following these steps:

  1. Right-click the folder that’s slowing down File Explorer. Choose Properties from the menu.
  2. Go to the Customize tab.
  3. Set Optimize this folder for to General items. If this value is already set, select any other value from the list. After that, switch it back to General items.
  4. Check Also apply this template to all subfolders.
  5. Click Apply and OK to save changes.

If this problem occurs with multiple folders, you’ll have to repeat this solution for every affected folder. Some people reported that they solved this issue by setting the optimization to Documents (instead of General items), so you might want to try that as well.
