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:
