Hi again! I'm using Delphi 6 and ZipMaster 1.70 with the latest dll's. I have set the ExtrBaseDir to a temporary directory at runtime. Extracting files work flawless. But, if I put a FileListBox on the form and set the directory to same as ExtrBaseDir I got the error: Error - no zip file specified! If I remark the line where I specify the directory for the FileListBox, it works without error again. What am I doing wrong here? /Stefan
