Vista - Upload multiple documents - zip files not visible

Today I worked on one issue and would like to share the design behavior of it so that we can keep a note and resolves the forthcoming issues in flexible manner.

Problem Description:

When we try to do "Upload Multiple Documents", we are able to locate our files on our laptops except for zip files.

For some odd reason, we can't see our zip files when choosing "Upload Multiple Documents". When we choose the Upload Document option, we are able to locate our zip files.

Machine Configuration:

·         Windows Vista with latest service packs

·         Office 2007

·         Internet explorer 7.0

Resolution:

Did some research and found the Microsoft KB which suggest that it is a design behavior with windows vista machines and needs registry modifications to fix it completely.

KB article: http://support.microsoft.com/kb/2002760  

Fix Suggested:

To fix this problem you need to delete the following registry keys. 

HKEY_CLASSES_ROOT\CLSID\{E88DCCE0-B7B3-11D1-A9F0-00AA0060FA31} 
HKEY_CLASSES_ROOT\CLSID\{0CD7A5C0-9F37-11CE-AE65-08002B2E1262}

Workarounds available:

1)      Document Library explorer view

2)     Document library single file upload

3)     Create a network share

Note: In above scenarios, we need to transfer the ticket to desktop support team if we don’t have rights to do any kind of registry changes on user’s machine.
