Consult VCLUNZIP how to extract the volume classification format package-CodePudding

I have a compressed file, is the volume classification, a total of 2 volume classification, the file called: file. Z01, file. Zip.
I use VCLUNZIP decompression, no matter which one extract, can succeed,

Form1. VCLUnZip1. ZipName:='file. Zip.//to be decompressed file
Form1. VCLUnZip1. ReadZip;
Form1. VCLUnZip1. Destdir:='234' d: \;
Form1. VCLUnZip1. MultiMode:=mmBlocks;
Form1. VCLUnZip1. DoAll:=True;
Form1. VCLUnZip1. RecreateDirs:=true;
Form1. VCLUnZip1. FilesList. Add (' *. * ');
Form1. VCLUnZip1. OverwriteMode:=Always;
Form1. VCLUnZip1. OnTotalPercentDone:=form1 VCLUnZip1TotalPercentDone;
Form1. ProgressBar1. Max:=100;
Form1. ProgressBar1. Position:=0;
Form1. VCLUnZip1. UnZip;

no matter my VCLUnZip1 ZipName point to which files, all can't extract,
This code is can extract the compressed file of volume classification,

Expert advice, genuflect is begged,
