Books Minium can’t open

Minium does not open DRM-protected books. That includes most books bought from the Kindle store, Kindle books in the KFX format and Print Replica books. Books from stores that sell DRM-free files, and public-domain books, work.

A book shows “File missing”

If a book’s file is gone from the device, the book stays in your library and shows “File missing”. Delete the book, then add the file again. Your reading position, quotes and collections come back; bookmarks do not.

Questions

Does Minium need an account?: No. There is no account, and nothing is uploaded.
Does it sync between my devices?: Not yet. Your library lives on the device.
Why did my book fail to import?: The message gives the reason: an unsupported format, DRM, a damaged file, or a file too large to open on the device.
Does Minium come with books?: Yes: a few public-domain books from Project Gutenberg.
What happens when I delete a book?: You get a few seconds to undo. After that the file is removed. Minium keeps your reading position and your quotes, so the book picks up where you left off if you add it again; Settings → Privacy can clear the positions, and quotes are deleted in Quotes.
