@billbonza, The WinZip people answered my query. I am afraid it does not help a lot. Here is my query and their amswer:
System: Vista SP1 32bit
> Is there a maximum size for a zip folder. Tried to zip a music file of
> 405MB. It shrunk it to 330MB, but then I could not open it. Message
> was: "Access to the compressed (zipped) folder 'G:\ music.zip' is
> denied". G is a pen drive from where the unzipped music file functions
Note that the message above is from the Windows 'Compressed folders'
utility rather than WinZip itself; the issue would appear to be at the
Can you start WinZip and access the file through the open archive
Compressed Folders can do basic zipping and unzipping, but there is
a large list of WinZip features that have no equivalents in Compressed
Folders, including the Zip and E-Mail feature, the ability to install
software from Zip files containing Themes and ScreenSavers, create
self-extracting Zip files that can be unzipped by users who don't have a
Zip utility, use and display comments within Zip files, create Zip files
that span multiple removable disks, split large Zip files into smaller
files for e-mailing, etc., locate recently used or downloaded Zip files,
or access the free WinZip add-on that lets you work with Zip files from
the command line or a batch file.
Currently XP always understands Zip files to be ShellFolders,
regardless of what application is associated with them. This behavior
appears to be governed by a registry key associated with the GUID for
compressed folders. But we have not had the chance to test the
repercussions of removing the key.
By the way, this same issue causes Zip file not to be included in the
list of recently used documents.
We also noticed that you can control whether compressed folders display
in Windows Explorer by doing the following:
If you open Windows Explorer and click on the + symbol next to
the folder mentioned above, the left side expands and you see no
compressed (zipped) folders on the left side.
Close Windows Explorer.
Re-open Windows Explorer and click on either the *icon* or the
*folder name that is hyperlinked* (of that same folder), the
left side expands and you see compressed (zipped) folders on
the left side.
To reset how compressed (zipped) folders display in Windows
Explorer you need to close and re-open Windows Explorer.
So if you don't want to see compressed folders on the left side of
Windows Explorer, always expand by clicking on the + symbol.
If you're using windows XP The drastic solution is to unregister
compressed folders. You would think that if compressed folders were not
installed, it would always gray out the button. But that is not the
case. Unregistering compressed folders has the side effect of removing
the content type value from the .ZIP key and this in turn causes IE's
special handling to be avoided. This can be accomplished by issuing the
command regsvr32 /u zipfldr.dll
