DBX with Compression

I&#x2019;m doing a forensics investigation in a set of DBX files.

The files are compressed or encrypted and, inside the file, I can find the specific string:

Inc. \
FileDescription DynaZIP-32 DBCS UnZIP DLL FileVersion 3.00.16
InternalName DynaZIP-32 DBCS UnZIP DLL
LegalCopyright Copyright (c) Inner Media, Inc. 1993-1998, All Rights Reserved.
LegalTrademarks DynaZIP is a Trademark of Inner Media, Inc. ( OriginalFilename
ProductName DynaZIP-32 DBCS 4
ProductVersion 3.00.16 :
SpecialBuild DBCS Version D
VarFileInfo $

I&#x2019;ve found a couple of components to do UnZip (from DynaZip), but using they in a application that I wrote, I&#x2019;m receiving a message like : &#x201c;Zip file error&#x2026; missing end signature&#x201d;. And: &#x201c;Zip file structure invalid&#x201d;.

I&#x2019;ve searched in a lot of sites for applications/services that use this kind of component, but without success.

Need your help.
