TZipFile.ExtractZipFile overwrite files?

[bnobre 0]

Hello everybody,

 

I'm using the class method below to extract the contents of zipped files:

 

https://docwiki.embarcadero.com/Libraries/Alexandria/en/System.Zip.TZipFile.ExtractZipFile

 

When extracting the zip file with this method, if there are files with the same name in the destination, will they be overwritten?

 

For example:

 

 

In the directory called test, the compact.zip file and a file called file1.txt are saved.

 

The compact.zip file contains a file1.txt file.

 

When extracting the file1.txt that is inside the compact.zip, will it overwrite the file file1.txt that is saved in the directory called test?

@bnobre YES, it will be replaced! But you can choice "what" file need extract be do it, then, you can put in another folder, for example!

Hi @programmerdelphi2k,

 

How are you?

 

Thx for your answer. 

 

In fact I really want him to replace it, but since I didn't find anything in the Embarcadero documentation I was in doubt if it really overwrites or not.

@bnobre try this...

var
  MyZIP: TZipFile;
begin
  MyZIP := TZipFile.Create;
  try
    MyZIP.ExtractZipFile('D:\MyZip\MyNewZip.zip', 'D:\MyZip');
  finally
    MyZIP.Free;
  end;

I tried,

 

He overwrote. 

 

I was just in doubt because in the Embarcadero documentation nowhere does it say that it overrides.

 

Thx
