From time to time, I come across newsposts which have par2 sets, but are just regular un-archived files which have been split using QuickPar. When altbinz downloads them, it just checks the par2 set's integrity and (since I have chosen that option), deletes the small .par file. Then I have to either (re)download the small .par or any of the other .par2's to open the set in QuickPar and rejoin the files, or I use HJ-split to merge the files.
Could you add the option to make par.exe rejoin the file or invoke some command-line utility to do so?
