What is all this stuff in the CKEditor folder?

Question

A while ago I downloaded the latest version (3.1) of the CKEditor text editor.

The directory name was ckeditor and I deleted the ckeditor/_source and ckeditor/_samples sub-directories, then I referenced the ckeditor.js file in my html pages, like so :

<script type="text/javascript" src="ckeditor/ckeditor.js"></script>

this works well. To make config changes, I have been modifying the ckeditor/config.js file.

However, as of late, I have been reading various web resources that say 'do not delete the _source' folder and other such ominous messages.

What is this _source folder?
What is all the stuff at the root of the ckeditor folder? and,
What is safe to remove from the folder?

Answer 1

The _source folder are all the uncompressed scripts, and should be used just to read, learn and modify the code (that you must compress afterwards). It shouldn't be available in a production server.

The *.HTML files are docs for you to read

The *.php and *.asp are server integration that you don't need in the way that you are using

The *_source.js and ckeditor.pack are used to work with the _source folder and then generate the compressed version

The adapters folder includes other integration (currently jQuery)
