Isn't there an unwritten law prohibiting document viewers changing the documents they open? If there is, ebook-viewer, part of calibre, doesn't respect it: diff -r m/META-INF/calibre_bookmarks.txt m1/META-INF/calibre_bookmarks.txt 1c1 < calibre_current_page_bookmark^7# *:eq(0) > *:eq(1) > *:eq(0) > *:eq(4) > *:eq(6) |0.19047619047619047 --- > calibre_current_page_bookmark^15# *:eq(0) > *:eq(1) > *:eq(0) > *:eq(8) > *:eq(43) |0.3619791666666667 The directories that I compared contain unzipped versions of the same epub file before and after an invocation of ebook-viewer. Probably calibre_bookmarks.txt was put in the epub file by ebok-viewer in the first place. Now one could say, that this is harmless, because it doesn't change the way the epub file will appear in any reader. But it changes filesize and timestamp, enough to make backup software notice. Hopefully, unchecking the "Remember the current page when quitting" in the Preferences is a workaround, but even then, it's just a workaround. ebook-viewer is welcome to have its own little database of bookmarks, but shouldn't annotate my books.
