I just wondered if anyone here knows of any software programs that allow you to organize your text files and images into folders and subfolders.

I started out with InDesign, but it doesn't let you work with your HTML (not to mention the fact that it's anal retentive). I then tried Sigil, which is wonderfully user-friendly - but it doesn't support subfolders. I was told Calibre does support folders, but it isn't working for me.

So I just wondered if there are any other options. I'm especially interested in programs that are user friendly and aren't too expensive.

Thanks.

P.S. I should mention that I'm using a Mac. I tried testing one program, only to discover that it's Windows only.
