Thanks very much for the excellent Calibre software, it really helps me a lot ;-)
But now there's a problem: I'm using Epubmerge plugin to merge more than 4000 epub files, (total size > 500.00MB) it reports: out of memory, and then exit...

Because our netword limit, I cannot reach and register on the Mobileread website, cannot get help from the author of Epubmerge...

Is there any other ways to merge more than 4000 epub files into one file, (total size > 500.00MB)?

Thanks again!
