Hi,

I have a book that has following files:
- index.htm (main page)
- toc.htm (toc)
- outro.htm (final word)

Then I have folders like this:
- ch01
- ch02
- ch03
- ....

In each folder there are few (changing between 1 to 6 or 7) files like this:
- 01-01.htm
- 01-02.htm
- 01-03.htm

for chapter 2 it would look like:
- 02-01.htm
- 02-02.htm
- 02-03.htm
- 02-04.htm
- 02-05.htm


this is the folder structure of my book.

I want to know if in Sigil, I can all import them into one epub, or if it is better to put all html files in one folder, or if Sigil is not able to combine or use external html files (and I need to combine all htmls manually in one chapter file)?
