Huge file handling

[nkonya-nk]

Hello,

I have a huge iso file, size is 35189686272 (33Gb), which has a tar archive in it 21948087095 (21Gb), and when i would like to add files to this iso with pycdlib, it does not throw any error/exception, the new file size on linux is 35190210560, so files were added, but if i mount this new iso, it shows that the previously 21Gb big archive is now only 4768226103 (4,5Gb). And if i try to extract the file it say the file is corrupted.

Same pycdlib code works just fine on smaller isos, which does not contain that 21Gb huge file.

Any idea what's wrong?

Thanks,
Nandor
