Problem with extracting volumes 001, 002


I've this case where packed application is packed with extension setup.001, setup.002 etc and up to setup.010.
I've checked and ArchiveProperties states that there are 10 volumes, yet when unpacking exception is thrown that setup.011 is missing?
Currently i am using Win7 x64 but i had same issues with Win Xp x32 and Win7 x32.
If you need more information please let me know.

Unfortunately I wasn't able to reproduce your issue. It would be nice if you somehow send me those 10 volumes.

Downloaded the volumes, you can delete them now. I will diagnose the problem today.

I confirm this bug, it will be fixed in 0.62

I need to dig deep inside 7-zip code, so I didn't find time for it in 0.62. I will see what can be done later. Sorry, but do not wait for a quick fix :(

No problem, i've put the unpacking project on hold anyway. Take care and I really appreciate your work on 7zip.

Is it still unsolved problem for 0.64 ?

With regards,
