Hi,

I am just working with the zipfile.py module and found out
a way to check if a zipinfo object is a dir:
I created 2 testzipfiles on Win2000 and Linux with info-zip.

I checked on Python 2.0 on Win2000 the following code
in a file called testview.py (my file)
The constants were taken from io.h of MSVC 6.0, the 
isdirzipinfo() function which accepts a zipinfo object
works at least under Win2000/Linux.

Perhaps you can integrate the code in a future release.

Bye

 Stephane

-------------------------- code follows ----------------

#/* File attribute constants for _findfirst() */

_A_NORMAL= 0x00   # /* Normal file - No read/write 
restrictions */
_A_RDONLY= 0x01   # /* Read only file */
_A_HIDDEN= 0x02   # /* Hidden file */
_A_SYSTEM= 0x04   # /* System file */
_A_SUBDIR= 0x10   # /* Subdirectory */
_A_ARCH=   0x20   # /* Archive file */

def isdirzipinfo(zi):
    isdir=((zi.external_attr & 0xff) & _A_SUBDIR) !=0
    return isdir
