[genome2k]

Adam presented this All-In-One IPDF released for iLiad 2.10, which links back to the iRex forum:

where the exexcutable file does not have an extension name,therefore I am not sure how to use this:

And here, Daudi privided a bundle of all 6 ipdf mods with a version inspector and iRex iPDF restorer.

I am not sure which one shall I install? Especially that ALL-in-One version I have no idea how to use it.

Beisdes, wpd's column-wise mode has a logging and non-logging version, I am not sure which very version Daudi has included in the package? If it was the logging version how can I delete the log files it generate?

Thanks guys
