Many classic ebooks and tutorials are released in CHM format, while Android doesn't support viewing these files by default. Even many popular ebook readers (such as Moon+ Reader, FBReader, Librera) have poor support for CHM format. In this case, we have to use specialized CHM readers such like SuperCHM, Chm Shelf and Chm Reader X.

htm2chm is a very practical CHM file (Microsoft Compiled HTML Help) creator, compiler, editor and decompiler I found a few years ago when searched "convert flash into CHM" in Google. At that time, I wanted to pack a flash file along with its related documents (HTML, TXT, ZIP, etc) as a CHM format e-book, so that I can take it anywhere.
