Make sure that the view is set to 'Detailed' and you have a few tabs that are related to the metadata of the files (Title.Put a file with a lot of media files in a drive (preferably, not the main one).If the folder has a lot of general files (scripts, for example), it will load in normally. This only happens if the folder's view is set to 'Details' and the metadata tabs are visible. If the files are on an SSD, it's manageable but if it's on a slow drive ( especially if it's a secondary drive and the chipset lets the drive to enter sleep mode) it can take a lot of minutes. When I'm working on a folder with a lot of media files (say, music for a game I'm developing), the File Explorer would take a long time to process the metadata.
