calibre User Manual, Release 2.56.0
The Files Browser gives youan overview of the various ﬁles inside the book you are editing. The ﬁles are arranged by
category,with text (HTML) ﬁles at the top, followed by stylesheet (CSS) ﬁles,images and so on. Simply double click
on a ﬁle to start editing it. Editing is supported for HTML, CSS and image ﬁles. The order of text ﬁles is the same
orderthat they would be displayed in, ifyou were reading the book. All other ﬁles are arranged alphabetically.
By hovering your mouse over an entry, you can see its size, and also, at the bottom of the screen, the full path to the
ﬁle inside the book. Note that ﬁles inside ebooks are compressed, so the size of the ﬁnal book is not the sum of the
individual ﬁle sizes.
Many ﬁles have special meaning, in the book. These will typically have an icon next to their names, indicating the
special meaning. For example,in the picture to the left,you can see that the ﬁles cover_image.jpg and titlepage.xhtml
have the icon of a cover next to them, this indicates they are the book cover image and titlepage. Similarly, the
content.opf ﬁle has a metadata icon next to it, indicating the book metadata is present in it and the the toc.ncx ﬁle has
aT icon next to it, indicating it is the Table ofContents.
You canperform many actions on individual ﬁles,by right clicking them.
You can rename an individual ﬁle by rightclickingit and selecting Rename. Renaminga ﬁle automatically updates all
links andreferences to it throughout the book. So all youhave to dois provide the new name, calibre will take care of
You can also bulk rename many ﬁles at once. This is useful if you want the ﬁles to have some simple name pattern.
For example you might want to rename all the HTML ﬁles to have names Chapter-1.html, Chapter-2.html and so on.
Select the ﬁles you want bulk renamed by holding down the Shift or Ctrl key and clicking the ﬁles. Then right click
andselect Bulk rename. Entera preﬁx and what numberyou would like the automatic numbering to start at, click OK
and you are done.
Sometimes, you may want to merge two HTML ﬁles or two CSS ﬁles together. It can sometimes be useful to have
everything in a single ﬁle. Be wary, though,putting a lot of content into a single ﬁle will cause performance problems
when viewing the book in a typical ebook reader.
To merge multiple ﬁles together,select them by holding the Ctrl key and clicking on them (make sure you only select
ﬁles of one type, either all HTML ﬁles or all CSS ﬁles and so on). Then right click and select merge. That’s all,
calibre will merge the ﬁles, automatically taking care of migrating all links and references to the merged ﬁles. Note
that merging ﬁles can sometimes cause text styling to change, since the individual ﬁles could have used different
Changing text ﬁle order
You can re-arrange the order in which text (HTML) ﬁles are opened when reading the book by simply dragging and
dropping them in the Files browser. For the technically inclined, this is called re-ordering the book spine. Note that
you have to drop the items between other items, not on top of them, this can be a little ﬁddly until you get used to it.
Marking the cover
E-books typically have a cover image. This image is indicated in the Files Browser by the icon of a brown book next
to the image name. Ifyouwant to designate some otherimage as the cover,youcan do so byright clicking on the ﬁle
and choosing Mark as cover.
