Criteria for 'blocking' files?

Is there a published document describing what will cause XP/SP2 to block
opening a file?

I have a zip file that will not unzip with Compressed Folders in XP, but
will with WinZip. Doing a binary paste of the contents of another zip file
that DOES open with XP and the file will open. So there is something about
the contents of the original zip file that XP is flagging. If I can find out
WHAT XP is flagging, I might be able to fix it.

Anyone?

Hi,

When using Internet Explorer to download files to a NTFS formatted
disk, for some file types (e.g. zip and exe), an alternate NTFS stream
is added to the file that contains information about what zone it comes
from (this way the original content of the file is untouched).

To view or (batch-)remove this alternate NTFS stream on downloaded
files, you can use the free command line tool Streams.exe for this:

Hi,

I have tried using Streams, and it indicates there is nothing to remove.
I have an application that creates the zip file (it is not downloaded by IE).
The file is created on a FAT32 file system (in Win CE), not NTFS. Opening
the file from a FAT32 drive, it is also blocked.
If I just paste the _contents_ of a non-blocked zip file, XP opens it
without blocking.
To make matters worse, there is no 'unblock' button available in the
properties dialog for the file.
There must be something about the contents that are being mis-interpreted by
the 'blocking check' I don't know what else it could be.
