RTF -> EPUB conversion error

[gondwild]

What is the feature of the .rtf file that calibre does not support? And what's the best way to proceed from here? (I don't particularly like the .rtf formatting, and would prefer to read the book in .epub, although the .rtf DOES in fact work on my Sony PRS 300)

Save your rtf as html and convert that

[peterloron]

If you are running on a Mac, you can use this Applescript snippet to quickly convert from RTF to HTML:

on open filelist
	repeat with i in filelist
		do shell script "textutil -convert html -extension html '" & POSIX path of i & "'"
	end repeat
end open

I have recently discovered textutil and it is a powerful little program.

I added your snippet to Applescript and saved it as an application.

Now, I have a powerful little drop converter.

Thanks for the tip
