Is there any way to index all thumbnails at once?

[582709]

I enjoy using feature 'see all under directory'.
Though, its thumbnail loading is always too long, so I'd rather index my photos and videos at once.
Do you know how to do it?

All thumbnails from the current directory should be preloaded now. To preload also those in subfolders branch view, you need to add the line
PreloadThumbnails=2
to wincmd.ini section [Configuration].
