Try this script:
Code: Select all
extlist("thumbs64", "epub", "a"); //add epub to the 64-bit Thumbnails
Yes, this fixed it! I tried it before but I guess I was using the 32 bit libraries, which is not needed anymore. Works right away with the current versions of DarkThumbs and XYplorer, no other steps needed.

I already had this entry.
It doesn't fix it for me.
The culprit must be one more setting ?

And from the very first post:
Also in the forums I found mention of a new Thumbs64Ext option in the ini file, again not sure if related but I added epub there as well. no change.

Add it to Document files.

Yes, my own post

One of the many things I had tried, but not combined with the right handler.

Fun fact: I don't have either pdf or epub thumbnails in Windows Explorer, but I don't care 'cause I never use it

Another fun fact: all the things you did to make EPUB thumbs work have been factory defaults for many versions.

Well, I finally upgraded!
Good to see that the latest XYplorer is still fully compatible with Windows 7, for most other software you have to dig into older versions and find out the latest one that worked.

It's already in Document files.

It should be in document files (and be checked there), and in thumbs64. If it still doesn't work, I'm out of ideas.

Try this,
tweak("PreviewEarlyFactory", 0);
If you are in thumbnail view when you run it, afterwards you'll need to refresh the epub thumbnails.

Works perfect now
Many thanks for your help.

I was curious what my PreviewEarlyFactory was set to on seeing this. My setting is "2". For history and background info see
viewtopic.php?p=208701#p208701 Don's post from last year.
Code: Select all
There are many ways to create thumbnails (IShellItemImageFactory, IExtractImage, GDI, native code), and many factors (file types, Windows version, installed CODECs and thumbnail handlers) that control performance, quality, problems. The situation is almost infinitely complex. It is pointless to expose all of this mess to the user -- it would make him a programmer rather than a user. But there are at least some options available to the user:
Configuration:
- Configuration | Preview | Previewed Formats
- Configuration | Preview | Thumbnails | Show thumbnails for RAW files
- Configuration | Preview | Thumbnails | Show thumbnails for non-images
- Configuration | Preview | Thumbnails | Quality
Tweaks:
- Thumbs64Skip
- Thumbs64Ext
- PreviewEarlyFactory
PreviewEarlyFactory originally controlled the sequence of attempts (which way to try first); in the meantime its function became it bit broader:
0 = [default] try IShellItemImageFactory first for some file types (internally hard-coded after years of experience), on failure fall back to IExtractImage
1 = try IShellItemImageFactory first for all file types, on failure fall back to IExtractImage
2 = try IExtractImage first for all file types, on failure fall back to IShellItemImageFactory
3 = try IExtractImage only for all file types, never try IShellItemImageFactory (added 20230309, not yet documented until now :) )
4 = [planned], bit OR-ed to the above values, making them 4,5,6,7: run IShellItemImageFactory in separate (64-bit) thread
