I have a lot of hi-res images in many folders, when I open a folder, windows explorer generates thumbnails for the images... But, because they are hi-res, it takes about 3 seconds for every image to have a thumbnail.
I'm looking for a way to generate thumbnails for selected folders without having to open them one by one and waiting for every image, also I have to scroll down to get more thumbs generated  :huh:

There seems to be this 3 1/2 year old solution on SuperUser

I know the search trick, but again.. I have to scroll down every 3 rows of images because windows explorer generates thumbnails only for visible area.  :-\

You might have to change file manager - or use an image viewer.
XYPlorer is quick to load thumbs (their quality isn't great though).

I dont know if any file manager copes really well with this.
I use directory opus - it has the option to load all thumbnails for the folder once opened. In spite of the fact that it caches thumbs, it is very busy for a good while on opening a folder with say a few hundred images. (I should check settings again, maybe it has used up all the space allocated to thumbnails).

Really? I pride myself to have the best thumbs in the business. Maybe you have the wrong settings.

Tick: Configuration | Preview | Image preview: | High quality image resampling
Untick: Configuration | Thumbnails | Super-fast thumbnails

Speed and quality is a trade off, of course.

^You're right Don

I had Super-fast thumbnails selected - when I deselect that the thumbnail quality is super.
As you say though:

There's even very few image viewers that are *really* quick in loading images.
I used use ExifPro but havent used it properly in a while - it does now have a
64bit version. Okay, just checked it -when the thumbs are cached, it's almost
instantaneous display  :up:
www.exifpro.com -
(shareware I think ~$20)
