EPUB cover thumbnails in Windows Explorer
With SageThumbs 2K, each EPUB book shows its cover in File Explorer instead of a generic icon. The cover is read straight out of the EPUB file, so an ebook folder looks like a shelf of books.
What you see
- The cover is extracted by SageThumbs' own Rust code; no ebook app or plug-in is involved.
- The Explorer preview pane shows the cover too, and pressing Space opens it in Quick preview.
Limits
- In OneDrive and other synced folders, files stored on the PC get thumbnails as anywhere else. Online-only files are left to the cloud app, since nothing is downloaded just to draw a thumbnail.
More you can do
- Other ebook formats get covers too: MOBI, AZW and AZW3, FB2, and comic archives such as CBZ and CBR.

Thumbnails not showing?
- Windows caches thumbnails, and a file it failed on once stays failed. In SageThumbs, Settings ▸ Advanced ▸ Rebuild thumbnail cache clears the cache and restarts Explorer.
- Make sure File Explorer's "Always show icons, never thumbnails" option is off, and that the format is ticked in SageThumbs Settings ▸ File types.
- Run
st2k doctorin a terminal. It only reads, checks the whole chain, and prints a fix under anything that is wrong.
