Compression of files
HTML Executable aims to generate the smallest publication and ebook files. This is especially done via file compression.
File compression
Strong compression algorithms such as LZMA are used in HTML Executable 4 (superior to the standard Zip method used in HTML Executable 3.1). Although these algorithms are generally fast, compressed source files may take some time before being displayed in publications. That's why you can define the level of file compression: it determines how hard the compression algorithms will try to compress your source files.
You can select between three levels: Minimum, Default and Best. The last level is "Disable": in this case there is no compression (files are just stored, uncompressed). The "Best" level will compress the slowest, but the compression ratio will be the highest.
It is up to you to choose the most suitable compression level according to the source files you are going to compile, the configuration of the publication's target computers, etc...
Notes:
- you can disable compression for specific files (especially for compact files like MP3 sounds or zip archives) via the File Properties.
- If the size of a compressed file is larger than its original size, HTML Executable stores it uncompressed.
Disable special HTML and text compression method: HTML pages and text-based files are first compressed using a special text compression algorithm, which results in a better compression ratio. However this method is a bit slower than the general compression algorithm. If you prefer to gain speed in compression and decompression, then turn this option on.
Enable size optimization: if you really want to save some additional bytes, then turn this option on. But in this case, the initialization of the publication can take more seconds.
Do not compress the search index data: for very large publications that must be run on old computers, this option may be useful. When it is enabled, the search index is not compressed, but stored. This will of course increase your publication .exe file's size.
