Ark doesn't support extracting multi-part zip files

Hello everyone, Ark from TDE and from KDE (4.8.3) can't extract a multi-part zip file. I wanted to know if it is a bug or if it is just a missing feature. I will upload soon my PCLinuxOS TDE to filefactory.com and since they have a size limit of 400mb, I will split my 1.5gb .iso file in 4 parts by zipping it in a multi-part zip archive. Q7Zip, File-roller, PeaZip support extracting these archives, so I wanted to know if it is normal that Ark doesn't support it? Maybe it could be a feature in the next TDE release? KDE don't even have it... -Alexandre
