Usage

1. For your project open "Project->Compiler Options->Other unit files" and add the path to the FPArchive units

2. In the "uses" clause of your unit add AbBase, AbBrowse, AbZBrows, AbUnzper, AbArcTyp

3. Create an unzip object:

UnZip := TAbUnZipper.Create(nil);

4. Set the directory where you want to extract the files to:

UnZip.BaseDirectory := '/path/to/extract';

5. To restore directories structure (optional) add this line:

UnZip.ExtractOptions := [eoCreateDirs, eoRestorePath];

6. Try to extract all CSV files (for example) from an archive file:

try
  UnZip.FileName := '/file/to/extract.zip';
  UnZip.ExtractFiles('*.csv');
except
  on E: Exception do
  begin
    //some error handling
  end;
end;

7. Free the created object:
