# Free Pascal/Delphi port of Unrar

This library allows you to unpack RAR (version 3-5) archives, password protected and not.

# Works in Delphi XE and Lazarus

# License

MIT
The code cannot be used to recreate RAR compression.

# Usage

Listing files:

```
uses Unrar;

var rar: TRarUnpacker;
    ADate: TDateTime;
    ASize: Int64;
    AName: String;
begin

rar := TRarUnpacker.Create('pass.rar', 'pass');  //can also be pass.exe - RAR SFX
  if not rar.CheckPassword then begin
    ShowMessage('Incorrect password!');
    rar.Free;
    Exit;
  end;

while rar.NextEntry(AName, ASize, ADate) do begin
    Memo1.Lines.Add(AName);
  end;

rar.Free;   
```

Extracting files:

```
var
  rar : TRarUnpacker;
  ADate: TDateTime;
  ASize: Int64;
  AName: String;
  F    : TFileStream;
  OutDir, FullPath: String;
begin
  OutDir := 'OutputDir\';   // destination directory

rar := TRarUnpacker.Create('pass.rar', '');
  try
    while rar.NextEntry(AName, ASize, ADate) do
    begin
      Memo1.Lines.Add(AName);

FullPath := IncludeTrailingPathDelimiter(OutDir) + AName;
      ForceDirectories(ExtractFileDir(FullPath));

F := TFileStream.Create(FullPath, fmCreate);
      try
        rar.Extract(F);
      finally
        F.Free;
      end;
    end;
  finally
    rar.Free;
  end; 
```
