If you need to access the thumbnails view or large icons view of explorer to navigate through images, then:
Enable offline access and select the folder(s) with images/video file to be available offline. Wait for these folders to sync and then you can work with those folders without experiencing hang or slowness.
If you DO NOT need thumbnails view and can work with just list view/details view of windows explorer to navigate images / video files then we recommend enabling following explorer optimizations:
- Disable automatic folder type discovery utilizing the Windows Registry Editor:

- Disable thumbnail previews for windows explorer
Making any changes to these settings will affect windows explorer globally and not just the Citrix Files drive.
