I have created two files from my personal data with winzip
some three months back. Now they are not opening thru
winzip and the following message is flashed:

"Winzip cannot open data1.cab because it is not in the
standard microsoft
cab format as defined in mid-1998. The "signature bytes"
required by the
microsoft cab specification are missing".

I had talked to winzip tech support group but they are
saying that it is a problem of microsoft.

please suggest.

With regards,
Rajnish
