DDzip - Unknown compression engine

[indigestion]

I'm trying to open a file with the extension *.dzip. When opening the file in a texteditor such as notepad, I find this:

//..

[DDZip]

ZipEngine=DDZip 1.1;

ZipCreation=06.10.2006 11:01:41;

ZipApplication=;

ZipContext=RAP_SINGLE_ZIP_V2;

ZipElement=001 of 001;

RecordCRC=-1363155428;

...//

It seems like the zipengine used is called DDZip 1.1. Have anyone ever heard about something like that?

I've tryed to open the file in winzip whitout any solution. (errormessage: "not valid archive")

Any suggestions?

Compressed files, these days anyhow, never have ascii text as a header or anything because everything is compressed. You may have a very old version of a dziped file or it may be something else. If you think there is a chance you think it could be malicious in any way when you uncompress it run an dzip -l filename to see what all files will be extracted. I say to do this because the v2.9 and probably previous versions of dzip have a coding error which can allow attackers to decompress files to any directory, like a startup directory. So if any files are not present when extracted is not good.
