How do you merge the pages under "book browser" on the left?

I downloaded an ePub file and it's split into many little sections and I would like to merge it into one single section.

Older readers had a 230kb size limit per xhtml file and loading smaller pages is much much faster than larger pages. So for the best loading speed splitting into files based on natural boundaries (chapters, etc) is simply good epub design.

So merging them all into a single file is generally *not* a good idea.

If you stll want to merge them, you can do so using by highlighting both files (they must be sequential) in BookBrowser and using Merge by using right-click.

More is explained in our Sigil User Guide. It has a short chapter on splitting and merging.

If you have two files to merge that have different css stylesheets, then making sure the class names from the two stylesheets do not conflict before merging is important.

All the time. But only to fix auto-split by calibre conversions due to STUPID Vellum use of multiple H# tags in chapter title-blocks.

My rule of thumb is file per each section (type)

Unless you have chapters split into multiple files, I would not recommend merging them.

If you have split chapters (looking at you, Gutenberg), you can use the merge function in Sigil to merge adjacent files.

Continuing with Gutenberg since they seem to have a love for splitting files at random so you can have multiple chapters in a file (an example would be a file with the last part of chapter 4, chapters 5 & 6 and the first part of chapter 7), I have merged all the files and then inserted split markers to allow splitting at chapter boundaries.

With Project Gutenberg books I merge all of the chapters together into one file, then figure out what excess crud can be removed and remove it, then add a sigil split marker in front of each chapter heading with a regular expression replace, then use the split on split marker command to split it properly.
