HTML docs to a single file

I have several large reference documents in my archives which are in HTML format. Essentially they are multiple page documents with images, some contain other formats as well. What I want to do is combine them into single files.

I know I could just take the pages from the particular folders and copy/paste them into another document format along with the images, but I'm looking for a faster way to do this.

Well, I found something to use. Adobe Acrobat will do this, although not exactly what I wanted, it works out ok. As long as the pages are linked together, then all you have to do is open the first page in Acrobat then instruct it to open all the linked pages. When it is done, you just save it as a .pdf and you have one single file containing what once took up many pages, images and directories.

I would have rather used something besides Acrobat but since no one seems to have had a better idea, I guess it works.
