Unarchiver marks files as directories

GoogleCodeExporter commented 8 years ago

Hi Dag:

I'm a fan of the Unarchiver on Mac, but I recently ran into an issue with a 
particular ZIP file (attached).  Though the ZIP file is extracted fine using 
the Archive Utility app on Mac and `unzip` in the terminal, all the files are 
marked as directories if The Unarchiver is used.

I've attached the ZIP file.  Please let me know if there's any other 
information you would like from me, like a logfile.  I tried to reproduce this 
with another project that builds a ZIP using exactly the same software, but it 
seems that this particular ZIP is problematic with The Unarchiver specifically.

As someone who also develops open-source software, I realise that you may not 
have the time to fix this soon (or maybe at all since it seems to be so rare to 
reproduce) -- but I thought you might like to have the information just the 
same.

Many thanks,

-Max

Looks like whatever program created that file erroneously set the OS to MS-DOS, 
and provided some random data in the file attributes field that, interpreted as 
MS-DOS, meant the file was marked as a directory.

I added an extra check for file size to be zero before believing that flag.

It's the zip file creator that is buggy, though, which is nothing unusual, 
there are millions of broken ones out there.
